Question

The molecular mass of a gas is
(select all that apply)
A. independent of the type of gas
B. the same number as the atomic (or molecular) mass, but measured in grams
C. dependent on the temperature
D. the mass of a mole of the gas

Answer 1

Answer:

b

Explanation:

Then the mass of the gas divided by the moles will give the molar mass. Now divide g by mol to get the molar mass. Since N has a molar mass of 14 g/mol and O has a molar mass of 16 g/mol, the formula N2O would produce the correct molar mass.
