Question

How many moles of oxygen in 36.55 grams of CO2

Answer 1

1.66 moles of oxygen

Step-by-step explanation:

Given data:

Mass of CO₂ = 36.55 g

Number of moles of O = ?

Solution:

Number of moles of CO₂ = mass/molar mass

Molar mass of CO₂ is 44 g/mol

Number of moles = 36.55 g/ 44 g/mol

Number of moles = 0.83 mol

1 mole of CO₂ contain 2 moles of oxygen.

0.83 × 2 = 1.66 moles of oxygen
