Answer:673.782 g
In this case, you are asked the copper mass and only given the copper volume( 75.2 cm^3 cubes). To answer this question, you need to know the copper mass density which was 8.96g/[tex] cm^{3} [/tex]. Then to find the mass, the calculation would be:
mass= density x volume = 8.96 g/[tex] cm^{3} [/tex]x 75.2 [tex] cm^{3} [/tex]= 673.782 g
