How do I solve this

Question

A cereal contains 11.0g of sucrose her 60.0 g of cereal. How many grams of cereal must be eating to consume 0.0424 moles of sucrose

Answer 1

Molar mass sucrose (C₁₂H₂₂O₁₁) = 342.3 g/mol

We can use dimensional analysis (unit factor method) to solve this problem:

mol sucrose x g sucrose/mol sucrose x g cereal/g sucrose = g cereal

0.0424 mol sucrose x 342 g sucrose/mol x 60.0 g cereal/11.0 g sucrose = 79.1 g cereal (3 sig. figs.)
