# If you place a 500 gram weight on a 1 inch x 1 inch paint sample is it the same weight per square inch if you place 5 1 inch samples under the same 500 grams?

The support provided by 5 samples would be 5 times greater than that of 1 sample, but the weight expressed by the 500 gram weight remains constant.

### How do you get the specific gravity of a mineral?

Fill a beaker with water, and weigh it. Weigh a sample of the mineral. That's the mass of the mineral. Put the sample in the beaker and weigh that. The weight of the water-filled beaker plus the weight of the mineral sample will be greater than the weight of the beaker with mineral sample and water. The difference is the weight of the displaced water, in grams. The volume of the mineral sample, in cubic…

### A sample of Se weighs 20.5 grams will a sample of V that contains the same number of atoms weigh more or less than 20.5 grams?

A sample of Se weighs 20.5 grams. Will a sample of V that contains the same number of atoms weigh more or less than 20.5 grams? (more, less): _______ Calculate the mass of a sample of V that contains the same number of atoms. _______ grams of V Answer: Since the atomic weight of V is smaller than the atomic weight of Se, each atom will have a smaller mass, and the sample will weigh…

### How much does a can of soda pop weigh?

The average 8oz aluminum pop can weighs 14 grams. 8 fluid oz of soda averages 1/2 pound. There are 453.5924 grams in a pound. So 1/2 pounds equals 226.7962 grams. So the soda alone weighs about 226.7962 grams Add the cans weight of 14 grams to the average weight of the soda 226.7962 grams. Which means the average can of pop weigh 240.7962 grams or .5552 pounds. I seen this data and decided to check…

### A 1.22g sample of an unknown has a volume of 1.73cm3. What is the density?

They use a number called a mole. This many atoms of an element equals its atomic weight in the periodic table. Molecular weight is the sum of atomic weight. Silver has an atomic weight of 108 grams/mole and Chlorine is 35.4 grams/mole. This makes AgCl 108 + 35.4 = 143.4 grams/mole. The % Chlorine is the atomic weight of Chlorine divided by the molecular weight of AgCl. 1 mole of AgCl would contain 35.4 grams…

### Where can you get some uranium?

The trade of uranium is very controlled and internationally surveyed. Some grams, as chemical reagent, but also with many approvals. If depleted uranium metal is OK unitednuclear.com often has 3 to 5 gram random weight samples for sale with larger samples when available (I bought a 29 gram sample from them once to donate to a school science lab to go with an element collection, it cost almost $200 and was smaller than a nickel)…

### How can you calculate grams per square meter?

The gram is a measurement of weight, and the square meter is a measurement of area. Formula: Basis Weight (in pounds) x 1406.5 Basis Size (in inches) = GRAMS PER SQUARE METER To find the Basis Size, refer to the chart in the related link. Example: Convert 25" x 38", 60 lb. Offset Paper to grams per square meter. 60 x 1406.5 25 x 38 = 88.8 Grams per square meter

### How many grams are in 240 mL of coca-cola?

Answer 1 mL of water = 1 gram. Therefore, there are 240 grams in a 240 mL sample of water. Coca Cola contains 39 grams of dissolved sugar which increase the weight of the total solution. Without knowing the specific gravity, it is impossible to get an accurate weight. A fair guess would be somewhere around 280 grams.

### How many grams of S are there in a sample of S that contains the same number of moles as a 96.3 gram sample of B?

The atomic weight of B is 10.8 g/mol 1. Convert grams of B to moles of B: moles B = 96.3 g B1 mol = 8.91 mol B10.8 g Multiply by moles per gram. Grams cancel out. The atomic weight of S is 32.1 g/mol 2. To convert 8.91 moles of S to grams of S: grams S = 8.91 mol S32.1 g = 286 g S 1 mol Multiply by grams per mole. Moles…

### How many grams of Co are there in a sample of Co that contains the same number of moles as a 45.6 gram sample of Cr?

The atomic weight of Cr is 52.0 g/mol 1. Convert grams of Cr to moles of Cr: moles Cr = 45.6 g Cr1 mol = 0.877 mol Cr52.0 g Multiply by moles per gram. Grams cancel out. The atomic weight of Co is 58.9 g/mol 2. To convert 0.877 moles of Co to grams of Co: grams Co = 0.877 mol Co58.9 g = 51.7 g Co 1 mol Multiply by grams per mole. Moles…

### Why is 2kg sample of lead denser than 10kg sample of iron?

Density is a weight per unit volume calculation. There could be different alloys or casting methods with subtle differences in density, or temperature variations in expansion and density. However: Every cubic centimeter of lead weighs 11.34 grams. Every cubic centimeter of iron weighs 7.86 grams. Thus, the density of lead (11.34 g/cc) is greater than iron (7.86 g/cc). This is independent of the actual weight and volume of the sample.

### A random sample of 10 miniature Tootsie Rolls was taken from a bag Each piece was weighed on a very accurate scale The results in grams were?

please help me A random sample of 10 miniature Tootsie Rolls was taken from a bag. Each piece was weighed on a very accurate scale. The results in grams were (3.087, 3.131, 3.241, 3.241, 3.270, 3.353, 3.400, 3.411, 3.437, 3.477) (a) Construct a 95 percent confidence interval for the true mean weight. (b) What sample size would be necessary to estimate the true weight with an error of + or - 0.03 grams with 95…

### Does density depend on how much sample you use?

Density is independent of the amount of material in a sample. A sample of a homogeneous substance used to find the density can have any volume. If a cm3 of the substance weighs 8.1 grams, then 10 cm3 will weigh 81.0 grams. We might consider water in a glass or bottle as an example. A small sample will have a given weight (mass) because water has a given density. Ten times that sample volume will…

### How many moles of carbon are there from the original sample of 11.0 grams of carbon dioxide and 4.50 grams of water with a combustion of 7.50 grams?

Look up the molecular weight of carbon dioxide in the periodic table. The formula for carbon dioxide is CO2, which means one atom of carbon and two atoms or oxygen per molecule of carbon dioxide. Carbon has molecular weight of 12. Oxygen molecular weight is 16. Total 12+16+16= 44 11 grams/44 grams/mole=0.25 moles of carbon The grams of water and combustion of 7.5 grams are totally irrelevant. They are only given to possibly confuse you.

### Which has the greatest number of atoms- 45 grams of Mg 45 grams of F 45 grams of P or 45 grams of Na?

In order to figure out how many atoms are in each sample, you would take 45, multiply it by 6.02 Ã— 1023, and divided by the atomic mass. Since two of the numbers (45 and 6.02 Ã— 1023) will be constants in all of the samples, the number of atoms will differ in each sample due to the atomic mass. 45 Ã— (6.02 Ã— 1023) / atomic mass in grams = number of atoms You…
