So to solve for this, let us calculate first the number of moles of hcl using the ideal gas equation.
00:07
We have pb, that's equivalent to nrt.
00:10
So we'll be solving for the number of moles.
00:12
So number of moles of hcl, that's equivalent to pv over rt.
00:17
So the pressure is 0 .576 this is atmospheres atm, multiplied by the volume, which is equivalent to 10 .7 this liters, and then divided by r, 0 .506 .2 .2.
00:30
This is liters 80 m per mole kelvin.
00:34
Okay that's the unit for r and then the temperature is 119 degrees celsius.
00:38
So we need to add 2 173 for this to be in kelvin.
00:41
So as you can see we'll be able to cancel the units.
00:44
Letters and then unit for temperature.
00:46
The remaining unit now is moles of course.
00:48
So number of moles of hcl is 0 .192.
00:51
This is a mole of htl...
