Hi there.
00:04
In this question, we have volume of a gas in liters, and we want to convert that to moles of the gas.
00:13
And we are told that we are at stp, which is standard temperature and pressure.
00:21
So to convert from volume to moles of a gas or from moles to volume of the gas, we can use molar volume.
00:28
And molar volume is the volume of one mole of the gas.
00:32
Since it's a gas, that volume is affected by temperature and pressure.
00:38
However, at stp, the molar volume of any gas is 22 .4 liters.
00:46
Or, in other words, one mole of any gas, in this case, we're working with hydrogen, is equal to 22 .4 liters...
