Answer:
37.62 g
Explanation:
First we convert 6.9x10²² atoms of C₁₂H₂₂O₁₁ to moles, using Avogadro's number:
- 6.9x10²² atoms ÷ 6.023x10²³ atoms/mol = 0.11 mol
Then we convert moles of C₁₂H₂₂O₁₁ to grams, using its molar mass:
Molar mass of C₁₂H₂₂O₁₁ = (C molar mass)*12 + (H molar mass)*22 + (O molar mass)*11 = 342 g/mol
- 0.11 mol * 342 g/mol = 37.62 g
