Question

Convert into mole
A. 12 g of oxygen
B. 20 g of water
C. 22 g of carbon dioxide ​

Answer 1

Answer:

I think it's a.12g of oxygen or b.20g of water

Answer 2

Molar mass of compounds or elements

Oxygen:- O2 => 2 × 16 = 32

Water :- H2O => 1 × 2 + 16 = 18

carbon dioxide:- CO2 => 12 + 16 × 2 = 12 + 32 = 44

conversion into mole

Oxygen => 12/32 = 0.375

water => 20/18 = 1.111

carbon dioxide => 0.5
