You have 15g of sodium iodide (Nal), which has a molecular weight of 150 g/mol. You place it all in a beaker and fill the beaker

bogdanovich [222]

Answer:

A. 0.1 M

Explanation:

Given data

Mass of NaI (solute): 15 g

Molar mass of NaI: 150 g/mol

Volume of solution: 1 L

Step 1: Calculate the moles of solute

$15g \times \frac{1mol}{150g} = 0.10mol$

Step 2: Calculate the molarity of the solution

The molarity of the solution is equal to the moles of solute divided by the liters of solution.

$M = \frac{0.10mol}{1L} =0.1M$

The solution is 0.1 M.
