Question

We add 1.4 moles to 700 mL of water what is the molarity?

Answer 1

Answer: The molarity of solution is 2 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n\times 1000}{V_s}$

where,

n = moles of solute = 1.4

$V_s$ = Volume of solution in ml = 700 ml

Now put all the given values in the formula of molality, we get

$Molality=\frac{1.4\times 1000}{700}=2mole/L$

Therefore, the molarity of solution is 2 M
