Answer:
1.403x10²⁴ molecules
Explanation:
In order to calculate how many molecules of CO₂ are there in 102.5 g of the compound, we first convert grams to moles using its molar mass:
- 102.5 g ÷ 44 g/mol = 2.330 mol CO₂
Now we convert moles into molecules using Avogadro's number:
- 2.330 mol * 6.023x10²³ molecules/mol = 1.403x10²⁴ molecules
