You can put this solution on YOUR website!
With our working formula ----> PV=highlight%28n%29RT,
see highlighted "n" equals the number of moles. But the problem states that "each" has 1.35 moles. Having said that, isn't your only solving for "1" Volume? (take note, STP, -- no change in Pressure & Temp.)
Considering too, each gases stated have different Molecular weight, how could they be then have the same number of moles?
.
For the given, we solve for V?
101.325%28V%29=%281.35%29%280.0821%29%28273.15%29
cross%28101.325%29V%2Fcross%28101.325%29=30.275%2F101.325
V=30.275%2F101.325
highlight%28V=0.30L%29, Answer
Thank you,
