Answer:
16.791 grams
Step-by-step explanation:
The density formula is:

Rearrange the formula for m, the mass. Multiply both sides of the equation by v.


The mass of the gold nugget can be found by multiplying the density and volume. The density is 19.3 grams per cubic centimeter and the volume is 0.87 cubic centimeters.

Substitute the values into the formula.


Multiply. Note that the cubic centimeters, or cm³ will cancel each other out.


The mass of the gold nugget is 16.791 grams.
