Answer:
0.187 mol
Explanation:
A solution is created by dissolving 10.0 grams of ammonium chloride in enough water to make 315 mL of solution.
The formula of ammonium chloride is NH₄Cl and its molar mass is 53.49 g/mol. We can use this information to calculate the moles of ammonium chloride associated with 10.0 grams.
10.0 g × (1 mol/53.49 g) = 0.187 mol
