Question

use the densities of iron and aluminum that you calculated in experiment 33 to answer the questions. what is the mass of a sample of iron that has a volume of 4.5 ml?4.5 ml? mass of iron: g

Answer 1

The density of iron is 7.874g/cm3 and the density of aluminum is 2.70 g/cm 3.

By using these density we can find out mass by given formula;
ρ = m/V
putting values in above for 4.5ml volume of iron ;
m= 7.874g/cm3 /4.5ml
m=1.749g/cm3 ml.
