What is the mass,in grams, of 2.75 L of CO2 gas
frez [133]

Answer:

mass of CO₂ = 5.402 g

Explanation:

At STP, 1 mole of any gas takes up 22.4L of volume

Thus, 1 mole = 22.4 L

1 L = 1 mole ÷ 22.4

Therefore, 2.75 L = 2.75 mole ÷ 22.4 = 0.123 moles

Molecular weight of CO₂ = 44 g/mole

mass of CO₂ = molecular weight * number of moles = 44 g/mole * 0.123 moles

mass of CO₂ = 5.402 g
