Question

Convert into mole 12 gram of oxygen gram 22 gram of carbon dioxide

Answer 1

Answer:

Answer. Here we are given the mass of oxygen gas as 12 grams. Molar mass = 2×16 = 32 grams.

Answer 2

Answer:

no of mole of oxygen is 2/3

no of mole of carbon dioxide=0.5

Explanation:

$no \: of \: mole = mass \: of \: a \: substance \div molar \: mass \: of \: a \: substance \\ \\ no \: of \: mole \: of \: oxygen = 12 \div 16 \\ \\ \\ \\ so \: no \: of \: mole \: of \: oxygen \: is \: 2 \div 3$

$similrly \: for \: carbon \: dioxide \\ \\ \\ \\ no \: of \: mole \: of \: carbon \: dioxide = 22 \div 44 = 0.5 \\ \\ \\ so \: no \: of \: mole \: of \: carbon \: dioxide \: is \: 0.5$
