Question

Josh prepares a solution by mixing sodium nitrate and water. To calculate the molarity of the solution, Josh should calculate the moles of which substance, and why?

sodium nitrate, because it is the solvent
sodium nitrate, because it is the solute
water, because it is the solvent
water, because it is the solute

Answer 1

C: sodium nitrate, because it is the solute

Step-by-step explanation:

Answer 2

sodium nitrate, because it is the solute

Step-by-step explanation:

To find the molarity of the solution, Josh should determine the number of moles of the sodium nitrate.

Molarity is defined as the number of moles of solutes in a given volume of solution.

Molarity =
`(n)/(v)`

n is the number of moles of solute

v is the volume of solution
