## What is the volume and weight of a mole of oxygen?

Volume and weight of the substance is calculated using its molecular weight, density and number of moles. Oxygen weighs 0.001429 gram per cubic centimeter or 1.429 kilogram per cubic meter, i.e. density of oxygen is equal to 1.429 kg/m³; at 0°C (32°F or 273.15K) at standard atmospheric pressure .

What is the density of oxygen in kg m2?

Oxygen weighs 0.001429 gram per cubic centimeter or 1.429 kilogram per cubic meter, i.e. density of oxygen is equal to 1.429 kg/m³; at 0°C (32°F or 273.15K) at standard atmospheric pressure.

### How do you find molar mass and formula weight?

Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.
