10 g of sugar was added to water weighing 100 g, calculate the number of sugar molecules

10 g of sugar was added to water weighing 100 g, calculate the number of sugar molecules in the solution, based on the formula C12H22O11.

First, we calculate the molar mass of sucrose.

M (C12H22O11) = 12 * 12 + 22 * 1 + 11 * 16 = 342 g / mol

Knowing the molar mass, we find the amount of the substance.

n (C12H22O11) = 10/342 = 0.029 mol

Multiplying the resulting value by Avogadro’s number, we find the number of molecules in the solution.

N (C12H22O11) = 0.029 * 6.02 * 10 ^ 23 = 1.76 * 10 ^ 22

Answer: 1.76 * 10 ^ 22 molecules

The mass of water does not affect the calculation, it is given in the conditions for distraction.
