How many grams of glucose are needed to prepare 400. ml of a 2.0%(m/v) glucose solution?

8 grams of glucose are needed to prepare 400. ml of a 2.0%(m/v) glucose solution.

Explanation:

Volume of the solution = 400 mL

Mass by volume percentage of the solution = 2%

Mass of the glucose = m

The mass by volume percent is given by formula ;

m = 8 g

8 grams of glucose are needed to prepare 400. ml of a 2.0%(m/v) glucose solution.
