Question 3 (5 points)
A solution is made by dissolving 0.75 moles of NaCl in enough water to give a final volume of 0.5 L.
What is the molarity of the solution?
0.375 M
1.5 M
0.67 M
3 M

Answer 1

Answer:

$\huge\boxed{\sf M = 1.5\ M}$

Explanation:

Given data:

No. of moles = n = 0.75 mol

Volume = V = 0.5 L

Required:

Molarity = M = ?

Formula:

M = n / V

Solution:

Put the given data in the above formula.

M = 0.75 / 0.5

M = 1.5 M
