Answer to Question #103305 in General Chemistry for Naye

Question

2.89 lbs zinc to cm3 zinc

Answer 1

Convert lbs to grams:

1 lbs= 453.59 g,

$m=2.89*453.59=1310.88$ grams.

Knowing the density of zinc $\rho=7.13 g/cm^3,$

calculate volume in cm3:

$V=\tfrac{m}{\rho}=\tfrac{1310.88}{7.13}=183.85 cm^3.$

Answer: 183.85 cm3.
