Chapter 14, Problem 76E

Coniferin is glycoside (a derivative of a sugar) found in conifers, such as fir tress. When a 1.205 g sample of coniferin is subjected to combustion analysis (recall Section 3-3), the products are 0.698g ${\text{H}}_2\text{O}$ and 2.479 g ${\text{CO}}_{\text{2}}$ . A 2.216 g sample is dissolved in 48.68 g ${\text{H}}_2\text{O}$ , and the normal boiling point of the solution is found to be $100.068°\text{C}$ . What is the molecular formula of coniferin?
