Answer:

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:

                                                715\;mL \times\frac{39\;g}{100\;mL}

                                                = 278.85 g

When might a large volume of material have little mass
Natali5045456 [20]
A large volume of material will have a small amount of mass when the material in question is gaseous or porous, and therefore has a lot of space within it despite taking up a large amount of space overall.
