# Is O2 mass 16 or 32?

## Is O2 mass 16 or 32?

O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu.

## How many liters are in 1 mole of O2?

22.4 liters
The molar volume of an ideal gas is ~22.4 liters per mole (we’ll consider O2 to be an ideal gas for these purposes, and 22.4 is an approximation that varies with temperature, it’s 22.414 at 0C).

Is the mass of 1 mole of O and 1 mole of S same?

O molecules contains 6.022 x 1023 molecules. 1 mole contains 6.022 x 1023 entities (Avogadro’s number) Concept 1. One atom of sulfur has a mass of 32.07 amu; one mole of S atoms has a mass of 32.07 g.

What is the mass of the 02?

### How many moles are in O2?

One mole
One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

### What is the molar mass of O2?

15.999 u
Oxygen/Atomic mass

What is 1g mole?

(Often called gram-molecular weight.) A mass of a substance in grams numerically equal to its molecular weight. Example: A gram-mole of salt (NaCl) is 58.44 grams. Terms G. …

What is the mass of 1 mole of nitrogen atoms?

14 g.
Mass of one mole of nitrogen atoms is 14 g.

#### What is the mass of 2 moles of oxygen?

63.9976 g
per mole of oxygen. From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..
