Calculate the mass of copper in kilograms (density = 8.96 g/mL) with the same volume as 225.0 grams of gold (density = 19.31 g/mL).

Answers

Answered by DrBob222
mass = volume x density
Find the volume of the gold. That's v = m/d = 225.0/19.31 = 11.65 mL
Now the Cu, mass = v*d = 11.65 mLx 8.96 g/mL = ? grams. Convert to kg.
