Question

15 g of nacl occupy a volume of 75 ml. What is the molarity of the solution?

Answer 1

Answer:

I solved your question and the photo of the solution is above

Answer 2

The molarity of NaCl solution is 3.42 M

Explanation:

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Given mass of NaCl = 15 g

Molar mass of NaCl = 58.5 g/mol

Volume of solution = 75 mL

Putting values in above equation, we get:

$\text{Molarity of NaCl solution}=\frac{15\times 1000}{58.5\times 75}\\\\\text{Molarity of NaCl solution}=3.42M$
