Explanation:
Answer:
0.32M
Explanation:
Given parameters:
Number of moles of NaCl = 1.29moles
Volume of solution = 4liters = 4dm³
Unknown:
Molarity of solution = ?
Solution:
Molarity is one the ways of expressing the concentration of a solute in a solution. It is given as;
Molarity = 
The unit is given as M which is mol/dm³
Input the parameters and solve;
Molarity =
= 0.32mol/dm³ or 0.32M
