Asked by ANDY
A mixture of CO2 and an unknown gas was allowed to effuse from a container. The carbon dioxide took 1.25 times longer than the unknown gas to escape.Which of the following gases could the unknown one be
Choices
A: Cl2
B: CO
C: HCl
D: H2
E: SO2
I am going B
for this reason:
CO2 is 44.01
CO is 28.0102
so that means that CO is 1.25 times lighter...??
Is this correct??
So that means B is correct ???
Thanks
Andy

I agree although I solved the problem mathematically. I don't know how you used 1.25 and 44 to arrive at 28.
The ratio is to the square root of the molar masses so 44/(1.25^2 = 28 but 44/1.25 = 35
