A gelatin gel contains 4.0% gelatin by mass and has density 1.02 g/mL. Find the mass of gelatin, in grams, present in 250 mL of this gel (two decimals).

Numerical answer type, answer in g, tolerance 0.01.

Answer: 10.2 g

Mass of gel

= 250 \times 1.02 = 255.0

g. Gelatin

= 0.040 \times 255.0 = 10.20

g.
