25 g of aluminum chloride (AICI3) was dissolved in 100 g of water (H2O). Determine the mass fraction of the substance in the resulting solution.
The term mass fraction of a substance is the ratio between the mass of a given substance and the mass of the entire solution. It is calculated by the formula:
w = m-substance / m-solution;
Usually expressed as a percentage.
w = (m-substance / m-solution) * 100%.
w = (25 / (100 + 25)) * 100% = (25/125) * 100% = 20%.
Answer: the mass fraction of AICI3 in the solution is 20%.
