Hi, so to solve for this, we need to calculate first the number of moles of hbr.
00:09
Using the ideal gas equation, pv is equivalent to nrt.
00:15
So the number of moles of hbr will be equivalent to pressure volume over rt.
00:21
So the pressure is 180 m, the volume is 80 .1 liters.
00:26
The gas constant is 0 .0821 liters atm per mole kelvin.
00:33
The temperature is, this is stp, so 273 .15 kelvin.
00:42
I'm going to write first, sorry i forgot to write the temperature and pressure.
00:46
At stp, it means standard temperature and pressure.
00:49
Temperature is 273 .15 and then the pressure is 180 m.
00:53
So that means you can now cancel some units, liters, atm, and kelvin.
00:59
So we have 3 .57, this is moles of hbr.
01:06
So we could solve for the number of moles of hydrogen gas using stoichiometry.
01:12
We have 3 .57 moles of hbr produced.
01:16
Convert this to moles...
