Question

How many molecules of CO2 are there in 2.30 x 10^-2 mol of carbon dioxide ?

Answer 1

1.39 × 10^22 molecules of CO₂

Explanation:

We are given;

• 2.3 × 10^-2 moles of CO₂

We are required to calculate the number of molecules of CO₂

• We need to know that;

1 mole of a compound contains 6.022 × 10^23 molecules

• Thus, we can answer the question;

2.3 × 10^-2 moles will contain;

= 2.3 × 10^-2 moles × (6.022 × 10^23 molecules/mol)

= 1.386 × 10^22 molecules

= 1.39 × 10^22 molecules

Therefore, there are 1.39 × 10^22 molecules of CO₂
