2178 litres of CO2 is produced in the combustion reaction.
HOW TO CALCULATE VOLUME
- The volume of a substance can be calculated using the formula below:
Density = mass ÷ volume
- Firstly, we must calculate the number of moles present in 5.9 × 10²⁵ molecules by dividing by Avogadro number:
no of moles. = 5.9 × 10²⁵ ÷ 6.02 × 10²³
no. of moles = 5.9/6.02 × 10²
no. of moles = 0.98 × 10²moles
= 98moles
Moles = mass ÷ molar mass
Mass of CO2 = moles × molar mass
Molar mass of CO2 = 12 + 16(2) = 44g/mol
Mass of CO2 = 98 × 44
Mass of CO2 = 4312g = 4.312kg
- The volume of CO2 can be calculated as follows:
Volume = 4.312kg ÷ 1.98kg/m³
Volume = 2.178m³
Since 1m³ = 1000L
2.178m³ = 2.178 × 1000
= 2178 liters.
- Hence, 2178 litres of CO2 is produced in the combustion reaction.
