A 2.05 liter cube of zinc has a mass of 14623 grams. What is the density of Zn in g/cm3?
Remember that
The density is equal to divide the mass by the volume
D=m/V
we have
m=14,623 grams
V=2.05 liter
we have that
1 mL=1 cm^3
1 L=1,000 mL
so
2.05 L=2.05*1,000=2,050 mL=2,050 cm^3
substitute in the formula
D=14,623/2,050
D=7.1 g/cm3
