Ammonium Chloride Solution Mass Percent Calculation

What is the mass percent, %(m/m), of ammonium chloride (NH4Cl) in a solution prepared from dissolving 6.13 g of NH4Cl in 75.0 g of H2O?

Final answer: The mass percent of ammonium chloride (NH4Cl) in the solution is 7.55%.

Answer:

7.55%

Ammonium chloride (NH4Cl) is a common chemical compound used in various applications. When a solution is prepared by dissolving 6.13 g of NH4Cl in 75.0 g of H2O, the mass percent of NH4Cl in the solution is calculated to be 7.55%.

To determine the mass percent of NH4Cl in the solution, we need to find the mass of NH4Cl and the total mass of the solution. By adding the mass of NH4Cl (6.13 g) and the mass of H2O (75.0 g), we get a total solution mass of 81.13 g.

The mass percent formula is used to calculate the percentage of NH4Cl in the solution. By substituting the given values into the formula, we find that the mass percent is 7.55%. This indicates that NH4Cl makes up 7.55% of the total mass of the solution.

Understanding the concept of mass percent and how to calculate it is important in various scientific and chemical applications. By mastering this calculation, we can accurately determine the concentration of a substance in a solution.
