Question

what is the mass of 0.2 moles Carbon dioxide[Mr of carbon dioxide=44]

Answer 1

Given :

• Moles of Carbon dioxide = 0.2

• Molecular mass of Carbon dioxide = 44

To find :

• mass of carbon dioxide

Formula used :

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

where n = number of moles

Solution :

Moles of Carbon dioxide = 0.2

Molecular mass of Carbon dioxide = 44

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

$\implies 0.2 = \dfrac{mass }{44}$

$\implies 0.2 \times 44 = {mass }$

$\implies\dfrac{2}{10} \times 44 = {mass }$

$\implies \dfrac{88}{10} = {mass }$

$\implies 8.8g = {mass }$

Answer :

mass of carbon dioxide = 8.8 grams

Answer 2

8.08gm of carbondioxides for 44gm
