Question

The formula for calculating density, D, is D=MV, where M represents mass and V represents volume. For liquids, volume is often given in cubic centimeters (cc), which is the same as cm 3. If the density of an unknown liquid is 1.6 g/cc, what is the mass of 800 cc of the unknown liquid in grams (g)?

a. 0.002 g
b. 1.6 g
c. 500 g
d. 1280 g

Answer 1

The answer is; D

Density 1.6g/cc means that every 1(one) cubic centimeter of the liquid has a mass of 1.6 grams.

Then, what about 800 cubic centimeters – how much mass, in grams, will it have ?

= 1.6 * 800 = 1280 g
