Question

What is the concentration by % m/v if 67 g are dissolved to make 1.2 L of solution?

Answer 1

Answer:

5.583%

Explanation:

Concentration= Mass of solute in g / volume of solution in mL

Change into milliliters (1.2L x 1000) = 1200mL

67g /1200mL x 100 = 5.583%

Answer 2

Answer:

The concentration of the solution is

= 5.58%

Explanation:

We know that the concentration of the solution (m/v%) is calculated by dividing the mass of the solute by the volume of the solution in milliliters and then multiplying this by 100

Mass of the solute m = 67 gm

The volume of the solution = 1.2 L

= 1200 ml

The concentration in %m/v is

$=\frac{67}{1200}(100)$

= 5.58%

Therefore the concentration of the solution is 5.58%
