This problem gives us the following equation.
00:02
Co gas plus 2h2 gas forms methanol, c -h -3 -o -h gas.
00:16
And the first thing we want to do is find the limiting reactant.
00:20
So for this, we can do the ideal gas law for carbon monoxide and hydrogen gas separately to get the number of moles of each.
00:30
And once we have the number of moles of each, we can compare them to see which one is limiting in this case.
00:39
So i'll start with co.
00:43
And so for co, again, we have the ideal gas law, pv equals nrt.
00:50
We want to solve for n.
00:52
And so our p in this case is 232 millimeters of mercury, which we can divide by 760 to convert to atmosphere.
01:02
And that 0 .30526 atmospheres.
01:08
Our volume is 1 .50 liters.
01:14
N is our unknown.
01:17
R is 0 .082 -057 liter atmospheres per mole kelvin.
01:29
And our temperature is 305 kelvin.
01:34
And so we can rearrange this equation to solve for n...
