Therefore, 12 g of oxygen gas has 0.375 moles.

## How many moles are in 1 gram of oxygen gas?

For one gram atomic weight of oxygen with atomic weight of 16 grams, one mole of oxygen also contains 6.022 × 10^{23} oxygen atoms. Similarly, for one gram atomic weight of silicon with atomic weight of 28 grams, one mole of silicon still contains 6.022 × 10^{23} silicon atoms.

## How do you convert from mole 12g of oxygen gas to Class 9?

(a) 12 g of oxygen gas

- Given mass of O
_{2}= m = 12g. - Molar Mass of O
_{2}= M = 32g. - Given mass of H
_{2}O = m = 20g. - Molar Mass of H
_{2}O = M = 18g.

## How many moles of oxygen are in 5 grams of O2?

As we know 1 mole of O2=32gm,as theatomic mass of O2=16amu so the mol mass and the molecular mass is equals to 32amu…means 32gm…as per question 5 mole so directly multiplying we can get our answer that is 160 gm… When you say oxygen , O2 is considered. So , 5 moles of O2 will be 16 × 5 = 160 gms ….

## How many moles are in 16g of oxygen?

16 g is equal to 0.5 mole of oxygen molecule.

## What is number of mole?

A mole is defined as the mass of the substance which consists of the equal quantity of basic units. Example atoms in 12 grams are the same as 12C. A mole fraction indicates the number of chemical elements. … One mole of any substance is equal to the value of 6.023 x 10^{23} (Avagadro number).

## How do I calculate moles?
