Question

Determine the mass in grams of a gold sample which occupies a volume of 16.39 mL? Gold has a

density of 19.3 g/mL.
a. 0.118 g
b. 0.316 g
c. 0.849 g
d. 1.18 g
e. 316 g

Answer 1

Answer: 316 g

Step-by-step explanation:

Gold is given as a volume but the answer is asked for as a mass. Use the density of gold to find the mass of gold in 16.39 mL.

16.39 mL x (19.3 g/mL) = 316.327 g = 316 g

Note that the mL cancel and you are left with grams.
