Question

) 22 g of Carbon dioxide [CO,
no into mole​

Answer 1

Given :

• 22 g of Carbon dioxide

To find :

• Moles of Carbon dioxide

Formula used :

$\sf n = \dfrac{given \: mass}{molar \: mass}$

where , n = number of moles

Solution :

Given mass of Carbon dioxide = 22 grams

Molar mass of Carbon dioxide = 12+(2×16)

=> 12+32

=> 44g

Molar mass of Carbon dioxide = 44

Now , we will find number of moles of carbon dioxide.

$\sf \implies n = \dfrac{given \: mass}{molar \: mass}$

$\sf \implies n = \dfrac{22}{44}$

$\sf \implies n = \dfrac{1}{2}$

$\sf \implies n = 0.5 \: moles$

Answer :

Moles of 22 gram Carbon dioxide = 0.5 moles
