What is the molarity of a solution prepared by dissolving 54.3 g of Ca(NO₃)₂ into 355 mL of water?

Question

Quizplus · Accepted Answer

First, we need to calculate the number of moles of Ca(NO₃)₂: moles = mass/molar mass = 54.3 g / 164.22 g/mol = 0.3309 mol Next, we need to calculate the volume of the solution in liters: 355 mL = 0.355 L Finally, we can calculate the molarity: molarity = moles of solute/volume of solution in liters = 0.3309 mol / 0.355 L = 0.932 M Therefore, the answer is B.
