calculate the no. of moles in 4g of carbon dioxide.

Open in App

Solution

Molar mass is defined as the mass of one mole (or 6.023 X 10²³ particles) of the substance. The molar mass of CO₂ is 44g. Thus
44g of CO₂ = 1 mole of CO₂
1g of CO₂ = ( 1 / 44) moles of CO₂
4g of CO₂ = (4 / 44) moles of CO₂
= 0.091 moles of CO₂.
