Final answer:
To calculate the mass of NaNO₃ required to prepare a solution with a specified molarity and volume, multiply the molarity, volume, and molar mass of NaNO₃.
Step-by-step explanation:
To calculate the mass of NaNO₃ required to prepare a solution with a specified molarity and volume, we can use the formula:
mass = molarity x volume x molar mass
In this case, the molarity is 0.222m and the volume is 33.9 mL. The molar mass of NaNO₃ is 85 g/mol. Plugging these values into the formula, we get:
mass = 0.222m x 33.9 mL x 85 g/mol = 63.8722 g
Therefore, 63.8722 grams of NaNO₃ is required to prepare 33.9 mL of the solution.
