Question

Analysis of a gas indicated that 46.2 % of its mass was carbon and 53.8% of the mass was nitrogen.

Answer 1

At 25oC and 751 torr, 1.05 g of the gas occupies 0.500 L.

What is the molecular formula for the gas?

Answer 2

Does it matter if this is an ideal gass because I would like to use PV = nRT = ideal gass law

Answer 3

using this equation i got moles = 0.020194 moles

Answer 7

CN or C2N2......?

Answer 8

any ideas?

Answer 9

yes

Answer 10

We can get the number of moles of the total gas with PV=nRT, see picture below, we get 0.020195 mol of gas

Answer 11

yes I got that

Answer 12

but what I need is how to get the molecular formula because I only have percent by mass
