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

(a) 12 g of oxygen gas

1. Given mass of O 2 = m = 12g.
2. Molar Mass of O 2 = M = 32g.
3. Given mass of H 2 O = m = 20g.
4. 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 ….
