A 262-mL sample of a sugar solution containing 1.22 g of the sugar has an osmotic pressure of 30.3 mmHg at 35°C. Determine the molar mass of the sugar. (1 mmHg = 0.00131atm) A 4.117-g impure sample of glucose (C&H12O5) was burned in a constant-volume calorimeter having a heat capacity of 19.65 kJ/°C. If the rise in temperature is 3.134°C, calculate the percent by mass of the glucose in the sample. Assume that the impurities are unaffected by the combustion process.

![3.
A 262-mL sample of a sugar solution containing 1.22 g of the sugar has an osmotic
pressure of 30.3 mmHg at 35°C. Determine the molar mass of the sugar. (1 mmHg
= 0.00131atm)
A 4.117-g impure sample of glucose (C&H12O6) was burned in a constant-volume
calorimeter having a heat capacity of 19.65 kJ/°C. If the rise in temperature is
3.134°C, calculate the percent by mass of the glucose in the sample. Assume that
the impurities are unaffected by the combustion process.
