So to solve for this, the first given, we have 1 .42 liters of hydrogen at stp, so that means we're going to have to use as the ideal gas equation, tb, that's equivalent to nrt.
00:19
So we are to find moles first, and equivalent to tb over our t.
00:26
Okay? and then let's substitute our values here.
00:31
Standard pressure, that's going to be 1 .80m.
00:35
And then volume is 1 .42 liters, right? and then our r is constant, 0 .0821 liters, 80m per more kelvin.
00:50
Okay, and then the temperature, standard temperature is 273 kelvin.
00:57
As you can see, we could cancel this.
01:00
And also liters.
01:02
That means our number of moles for this is 0 .06, 6336.
01:11
Okay, big gas.
01:15
Hcl, okay, rather...
