How many grams of AgNO₃ are needed to make 250.mL of a solution that is 0.135 M? A)0)0917 g B)0)174 g C)5)73 g D)9)17 g

Question

Quizplus · Accepted Answer

The formula for calculating the amount of solute needed to prepare a solution of known concentration is: mass = concentration x volume x molar mass First, we need to calculate the number of moles of AgNO₃ needed to prepare the solution: 0.135 mol/L x 0.250 L = 0.03375 mol Next, we need to calculate the mass of AgNO₃: mass = 0.03375 mol x 169.87 g/mol = 5.73 g Therefore, the best choice is C, with a mass of 5.73 g.
