What is the molar mass of a gas if 0.281 g of the gas occupies a volume of 125 mL at a temperature 126 °C and a pressure of 777 torr? I am not sure how to figure this out. I thought that maybe I could get the molar mass from the osmotic pressure but the example in my book doesn't use the same values. Any help would be greatly appreciated.

Molecular distances are usually given in nanometers (1 nm = 1 × 10-9 m) or in picometers (1 pm = 1 × 10-12 m). However, the angstrom (Å) unit is sometimes used, where 1 Å = 1 × 10-10 m. (The angstrom unit is not an SI unit.) If the distance betwee..
