Final answer:
When 6.22 g of NH₄Cl is dissolved in water, there are 0.1162 moles of NH₄Cl in solution.
Step-by-step explanation:
The molarity of a solution can be calculated by dividing the moles of solute by the volume of the solution in liters. In this case, we need to determine the number of moles of NH₄Cl in 6.22 g.
The molar mass of NH₄Cl is 53.49 g/mol. By dividing the given mass by the molar mass, we can calculate the number of moles: 6.22 g NH₄Cl / 53.49 g/mol = 0.1162 mol NH₄Cl.
Therefore, when 6.22 g of NH₄Cl is dissolved in water, there are 0.1162 moles of NH₄Cl in solution.
