Question

In 132 g of Co2 how many moles are present ??

Answer 1

Answer: 3 mole

Explanation:

molar mass of CO₂ = mass of carbon + 2( mass of oxygen ) = 12 + 2( 16) = 12 + 32 = 44

therefore 1 mole of CO₂ = 44 g

No of mole = given mass/ molar mass

                    = 132 / 44

No of mole  = 3 moles

Answer 2

Given: 132 grams of carbon dioxide.

To find: We have to find the number of moles.

Solution:

The number of moles of carbon dioxide gas can be determined by the below steps-

The formula of carbon dioxide gas is $CO_2$.

The atomic mass of C is 12 and oxygen is 16.

Hence the molecular mass of carbon dioxide gas is 12+16×2=44g.

44g of carbon dioxide gas has 1 mole.

Thus 132g of carbon dioxide gas has 132/44=3 moles.

132g of carbon dioxide has 3 moles.
