Question

Calculate the percent mass per volume, % (m/v), of a dextrose solution containing 7.00 g of dextrose in 2.00×102 mL of solution. Note that mass is not technically the same as weight, but the abbreviation % (w/v) is often used interchangeably with % (m/v).

Answer 1

Answer:

The mass per unit volume percentage is equal to 3.43%

Explanation:

given

mass=7 grams

volume = 2 * 102 ml = 204ml

The percentage mass per volume is given by

%(m/v) = w grams of solute * 100 / Volume of solution in ml

            = $\frac{7}{204}*100$

             = 3.43%
