How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles water in 27 grams
How is a sample oxygen different from a sample of a water?
Oxygen is just O and water is H2O
Fifty grams of water cooled from 50 degrees to 10 degrees if the specific heat of wayer is 4.2 hoe much was released?
If fifty grams of water cooled from 50 degrees to 10 degrees, and the specific heat of water is 4.2, 135 kJ of heat was released.
When is a sample of water said to be hard?
A sample of water is said to be hard when it does not form lather readily with soap.
If you have a 1.0cm3 sample of lead and a 1.0cm3 sample of glass You drop each in separate beakers of water How do the volumes of water displaced by each sample compare?
They're the same.
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 centimeters is equal to the weight of the displaced water, in grams. Calculate the specific gravity of the mineral by dividing the weight of the mineral sample by the volume of the mineral sample. Example: your beaker weighs 40 grams. Filled with water, it's 1040 grams. The sample of mineral weighs 160 grams. The beaker with the sample of mineral and water weighs 1179.7 grams. The mineral, and the beaker with water would have a combined weight of 1200 grams, but the beaker with mineral and water weighs 20.3 grams less than that, so the mineral sample is displacing 20.3 cubic centimeters of water. Given a mass of 160 grams and a volume of 2.03 CC, the specific gravity would be found by dividing 160 by 20.3. It's 7.85. (Which happens to be the specific gravity of some iron.)
A sample of water has a mass of 13 grams and volume of 13 milliters what is the density of water?
1 gm/ml
A sample of sweet corn weighing 175 grams was freeze dried The recovered solid weighed 122 grams What was lost?
53 grams of water was lost.
How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles water in 27 grams
How many pounds is 720ml of water?
The density of water is 1 gram per millilitre. That means this sample of water is 720 grams. Converting that to pounds, that is 1.587 pounds.
A sample of 90 g water was decomposed using electrolysis How many liters of hydrogen where produced at STP?
60 grams.
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 have ten times the mass of that volume of water. The density of water does not change if we examine water in a small glass and another sample of the same water in a gallon jug.
If a water sample contains 10 parts per million phosphorus how many grams of phosphorus would a liter contain?
10 milligrams
How many grams of magnesium are in the 1000 g sample of ocean water?
According to Castro & Huber's Marine Biology textbook, there is about 1.3 g of magnesium in 1000g of ocean water.
The volume of a sample of water is 20cm3 the mass of?
The volume of a sample of water is 20 cm3. The mass of this sample is closest to
How many joules are necessary to heat a sample of water with a mass of 46.0 grams from 0.0?
46 calories (or 192, 464 joules) for each Celsius degree.
Which sample would displace 8 ml of water if its mass was 20 grams?
The one which has a density of 2.5 g/ml (making its volume 8 ml).
