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

Answer 2

Answer:

The correct answer to this question is D 1280g.

Explanation:

Density defines as the product of mass and volume.

According to the question, $1^{3}$ centimeter signifies that the $1.6\:\text{g/cc}$ of  liquid has the same mass which is equal to 1.6 grams.

To find the density of $800\;\text{cc}$.

D =MV

Therefore, $D =800\times1.6 = 1280\;\;{g}$
