Question

convert into mole 12 gram of Oxygen gas. 20 gram of water.and
22 gram of carbon dioxide ​

Answer 1

Answer:

Oxygen gas 0.375 mole, Water 1.11 mole and Carbon dioxide 0.5 mole.

Explanation:

We know,

32g of Oxygen gas= 1 mole

So, 12g of Oxygen gas= (12/32) mole= 0.375 mole

Again,

18g of Water= 1 mole

So, 20g of Water= (20/18) mole= 1.11 mole

And,

44g of Carbon-di-Oxide= 1 mole

So, 22g of Carbon-di-Oxide= (22/44) mole= 0.5 mole
