Question

what is the density of a sheet of aluminum that has a volume of 328.4 cubic centimeters and a mass of 780 grams

Answer 1

Answer:

$\large\boxed{density=\dfrac{1950}{821}\ \dfrac{g}{cm^3}\approx2.375\ \dfrac{g}{cm^3}}$

Step-by-step explanation:

$density=\dfrac{mass}{volume}\\\\\text{We have}\\\\mass=780\ g\\volume=328.4\ cm^3\\\\\text{Substitute:}\\\\density=\dfrac{780g}{328.4\ cm^3}=\dfrac{780\cdot10}{328.4\cdot10}\ \dfrac{g}{cm^3}=\dfrac{7800}{3284}\ \dfrac{g}{cm^3}=\dfrac{7800:4}{3284:4}\ \dfrac{g}{cm^3}\\\\=\dfrac{1950}{821}\ \dfrac{g}{cm^3}$
