Hi, so to solve for this, we need to calculate first the number of moles of chlorine gas using the ideal gas equation, pv is equivalent to nrt.
00:13
So the number of moles of co2 will be equivalent to pv over rt.
00:19
Pressure is given, it's 0 .693 atm.
00:23
Volume is 8 .36 litres.
00:27
R is 0 .0821 litres atm per mole kelvin.
00:35
Temperature is 113 degrees celsius and then add 2 sub -entity, 0 .15, or let's just use 2 sub -entity.
00:45
Disturbance kelvin, cancel, unit for temperature, volume, atm, and the remaining units you can see here is moles.
00:54
So the number of moles of chlorine gas is 0 .1828 moles.
01:01
Now using stoichiometry, we will solve for the number of moles of hcl, not h2.
01:11
We have 0 .1828, this is moles of cl2 reacted, multiply the stoichiometric ratio as per the given balance equation, 1 mole of cl2 reacted will produce 2 moles of hcl.
01:25
So that's the moles of cl2 and this will give us 0 .3656 moles of hcl...
