Understanding the Problem

To solve this problem, we need to understand the concept of molarity and how it relates to the mass of a substance required to make a solution of a specific concentration. Molarity is defined as the number of moles of a substance per liter of solution. In this case, we are given a 1.50 M solution of NaNO3, which means there are 1.50 moles of NaNO3 per liter of solution.

Calculating the Number of Moles Required

First, we need to calculate the total number of moles of NaNO3 required to make 4.50 L of a 1.50 M solution. We can do this by multiplying the molarity of the solution by the volume of the solution in liters.

Molarity (M) = Moles of NaNO3 / Volume of solution (L)

Rearranging the equation to solve for moles, we get:

Moles of NaNO3 = Molarity (M) x Volume of solution (L)

Plugging in the values given in the problem, we get:

Moles of NaNO3 = 1.50 M x 4.50 L = 6.75 mol

Calculating the Mass of NaNO3 Required

Now that we know the total number of moles of NaNO3 required, we can calculate the mass of NaNO3 needed to make the solution. We are given the molar mass of NaNO3 as 85.00 g/mol. We can use this value to calculate the mass of NaNO3 required.

Mass of NaNO3 = Moles of NaNO3 x Molar mass of NaNO3

Plugging in the values, we get:

Mass of NaNO3 = 6.75 mol x 85.00 g/mol = 571.25 g
