Question

1. fill in the blanks with the correct options. when calculating the molarity of a solution, students must know the number of moles of the -- choose the correct answer -- and the number of liters of the -- choose the correct answer --. (dropdown options: solvent, solute, solution; clear all button)

Explanation:

First Blank (number of moles of the...):

Molarity ($M$) is defined as the number of moles of solute per liter of solution, given by the formula $M = \frac{\text{moles of solute}}{\text{liters of solution}}$. So, for calculating molarity, we need the moles of the solute.

From the molarity formula $M = \frac{\text{moles of solute}}{\text{liters of solution}}$, the volume used is the volume of the solution (since the solute is dissolved in the solvent to make the solution, and molarity depends on the total volume of the solution).

Answer:

solute

Second Blank (number of liters of the...):
