solve for volume with density and mass given

Question

Mass = 0.0098 x 10^{-5 mg and density of .879 g/ml what is the volume?}

 

Answer 1

ρ = m / V is the density formula.

 

 

Rearrange to solve for the volume:

 

ρV = m

 

V = m / ρ

 

 

0.0098 x 10^-5 mg = (9.8 x 10^-3) x 10^-5 x (10^-3 g)= 9.8 x 10^-11 g

 

 

Using the volume equation, V = 9.8 x 10^-11 g / 0.879 g/ml = 1.11 x 10^-10 ml
