Question

mass of 1 gram gas covered 1400 ml volume at ntp .Calculate the molar mass of the gas. Calculate the number of molecules of 1 ml of gas at ntp​

Answer 1

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.
