# A student measures a \(3.42\text{ g}\) sample of solid sucrose, \(\text{C}_{12}\text{H}_{22}\text{O}_{11}\) (molar mass \(342\text{ g/mol}\)), for a laboratory investigation. How many sucrose molecules are present in the sample?

A student measures a \(3.42\text{ g}\) sample of solid sucrose, \(\text{C}_{12}\text{H}_{22}\text{O}_{11}\) (molar mass \(342\text{ g/mol}\)), for a laboratory investigation. How many sucrose molecules are present in the sample?

- **A.** \(6.02 \times 10^{21}\)
- **B.** \(7.22 \times 10^{22}\)
- **C.** \(6.02 \times 10^{23}\)
- **D.** \(2.06 \times 10^{24}\)
