Question

what is the mass in grams of 2.00 cubic inches of gold given that the density of gold is 19.3 g/cm^3 ?

Answer 1

Density is equal to the mass divided by the volume.

D = m/V

where
D = density
m = mass
V = volume

We have the density and enough information to find the volume in theproblem. All that remains is to find the mass. Multiply both sides of this
equation by the volume, V and get:

m = DV

2.00 (cubic inches) = 32.774128 cubic centimeters

m = 19.3 g/cm^3 *32.774128cm^3=632,461 g
