Answer 1

To calculate the number of CO₂ molecules in 0.0150 mol of CO₂, multiply the number of moles by Avogadro's number. In this case, there are approximately 9.033 × 10²² CO₂ molecules.

Step-by-step explanation:

To calculate the number of CO₂ molecules in 0.0150 mol of CO₂, we can use Avogadro's number (6.022 × 10²³) which represents the number of particles present in one mole of a substance. First, we convert the number of moles of CO₂ to the number of molecules by multiplying by Avogadro's number:

0.0150 mol CO₂ * 6.022 × 10²³ molecules/mol = 9.033 × 10²² molecules

Therefore, there are approximately 9.033 × 10²² CO₂ molecules in 0.0150 mol of CO₂.
