Question

If 0.250 g of a gas sample represents 1.05x10–2 mol, what is the molar mass of the gas?

Answer 1

Well, divide the mass by the molar quantity...

Explanation:

`"Molar mass"=(0.250*g)/(1.05xx10^-2*mol)=23.8*g*mol^-1`...if this is an elemental gas, the gas is likely neon....why can't it be oxygen or nitrogen?
