The mass fraction of a solute is determined by the ratio of the mass of the solute to the mass of the solution and is expressed as a percentage or fractions.
The mass of the solution is the mass of all the components of the solution, in this case, it is glucose and water.
Let’s find the mass of the solution m (solution) = m (glitch) + m (water), where m (glitch) is the mass of glucose, m (water) is the mass of water.
m (solution) = 10 + 100 = 110 g.
Determine the mass fraction of the solute, expressed as a percentage:
w = m (glitch) * 100% / m (solution) = 10 * 100% / 110 = 9.09%
