The mass of solute per 100 ml of solution is abbreviated as (m/v). mass is not technically the same thing as weight, but the abbreviation (w/v) is also common. how many grams of sucrose are needed to make 715 ml of a 39.0% (w/v) sucrose solution?

Amount of sucrose required = 278.85 g

Explanation:

(w/v)% = 39.0 %

Volume of the solution = 715 mL

39% (w/v) means 39 g of sucrose present in 100 mL of the solution.

Using unitary method,

For making 39% solution,

100 mL solution requires 39 g of the sucrose

therefore, 715 mL solution requires:

                                                = 278.85 g

answer; i do believe the correct answer is (river); /// good luck
