How much volume does 1 mole of a gas occupy at NTP?
PV=nRT. So at ntp P=1bar. If n= 1mole. R= .082. T=273K. Then 1V=1.273 .082. v=22.44 l of gas
What is the mass in grams of 1mole of oxygen?
The mass of 2.000 mol of oxygen atoms is 32.00 grams.
Molecular mass equals 2vapour density?
vapor density =density of gas/density of hydrogen gas=mass of a certain vol. of gas/mass of same vol. of hydrogen gas=mass of n molecules of gas/mass of n molecules of hydrogen gas=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas=molecular mass of gas/molecular mass of hydrogen gas=molecular mass/22 x vapor density=molecular mass
How much does 20 grams of water weigh as a gas?
20 grams. Its mass does not change when it changes from a liquid to a gas - only its volume (which is much larger - how much larger depending on the pressure of the gas).
Does gas have definite mass?
Yes. Gas Mass = sum of gas atoms= n(gas atoms).
How much mass does 1 mol of o2 gas have?
15.99 x 2 g
How could a chemist find out how much mass is given off as gas during a chemical change?
How could a chemist find out how much mass is given off as gas during a chemical reaction
What supports the idea that mass is conserved in a reaction that produces a gas as a product?
Trapping the gas and measuring its mass...
What elements mass is 30 and a noble gas but not neon?
There is no such noble gas with an atomic mass of 30. The mass of neon is 20 and the mass of the next noble gas, argon, is 40
What is a gas and has as mass number of 19?
Fluorine is a gas with a mass number 19.
Why is it that when you add pressure to a bottle it increases its mass?
when you add pressure to a molecule it increases because pressure is like gas and when there is to much gas it has to expand.
Why does the density of Saturn is much less than earth's even though it is much bigger in size?
Saturn is a planet made out of mostly gas. As gas has little mass, it is less dense than Earth. Remember that density is proportional to its mass and surface area.
