CHEMISTRY | MOLE CONCEPTS | Question 12
How many grams of carbon dioxide are there in a container with a volume of 4.5L at STP?
-
DATA GIVEN:
Volume ofCO2 Ξ 4.5L
Molar volume Ξ 22.4dm3/mole
Asked:
Mass ofCO2
-
Mass of CO2
Mass of CO2
Mass = mole × molar mass
Mole = volume /Molar mass
= 4.5dm3 /22.4dm3/mole
= 0.20089mole
Mole = mass /Molar mass
Mass = mole × molar mass
= 0.20089 × 44g/mole
= 8.839g
8.839g of carbon dioxide was found in a container
