What else can I help you with?
Why you should only put as much water as you need into the kettle to boil and not just fill you up?
As mass in a sample increases, it requires more energy to alter the temperature. The energy required is equal to the specific heat of the sample, multiplied by the mass, multiplied by the temperature change.
How many moles is 0.75g of Na2CO3?
The formula mass of sodium carbonate, Na2CO3 is 2(23.0) + 12.0 + 3(16.0) = 106.0Amount of Na2CO3 = mass of sample/molar mass = 0.75/106.0 = 0.00708mol There are 0.00708 moles of Na2CO3 in a 0.75g pure sample.
If A sample of metal has a mass of 94.5 grams and a volume 7 cubic centimeters what is the density?
Based on the formula Desnity= Mass/Volume. The answer would be 13.5 g/cm3
A 50 0 mL urine sample has a mass of 50.7g The specific gravity of the urine is?
1.014 g/ml
When the tempurtare of a sample of water is 5 degrees c the water is?
Too cold to remain it very long
The volume of a sample of water is 20cm3 the mass of?
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
If sample of drinking water was contaminated with 15 ppm by mass of chloroform then express in percent by mass?
The concentration of chloroform in the drinking water sample can be expressed as 0.0015% by mass. This is because 15 ppm represents 0.0015% of the total mass of the sample.
A saturated soil sample has a mass of 1.38kg and a volume of 0.6 liters. After dried in a oven for 24 hours the mass of th soil sample is 1.13kg. calculate mass of water?
Initial water content in the soil sample can be calculated using the initial mass and final mass after drying. Initial water content = (Initial mass - Final mass) = 1.38 kg - 1.13 kg = 0.25 kg. This is the mass of water in the soil sample.
A sample of zinc is placed in a graduated cylinder. The initial volume of water= 15.0mL and final volume of water and sample= 24.0mL. Determine the mass of the sample of zinc?
what?
A sample of 1 mL of water has a mass of about?
The mass of 1 mL of water is 1 g.
How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
What measurements must you make to find the density of a sample of matters?
density = mass / volume. so you need to weigh to find the mass. To find the volume submerse in water and record the displacement of water to find the volume.
If 213 J raises a sample of water C what is the mass of the water?
6.2 g
If J raises a sample of water 8.2 C what is the mass of the water?
6.2 g
If 213 raises a sample of water 8.2 C what is the mass of the water?
6.2 g
If 213 J raises a sample of water 8.2 what is the mass of the water?
6.2 g
Which best describes the total mass of a sample of water when it condenses from a liquid to gas'?
The total mass of a sample of water remains constant when it condenses from a liquid to gas, according to the law of conservation of mass. Although the state of the water changes, the mass does not change during the phase transition. Therefore, the total mass of the water in both the liquid and gaseous states is the same.
