Question

With a volume of 33.69 ml and a mass of 43.808 g what is the density?

Answer 1

Hello !

There is a very simple formula for density that will help you to solve the problem :
ρ - density
V - volume
m - mass
_______________
ρ = m/V (g/m³)

You have ml,not m³. We know that :
1 l = 1 dm³ = 10⁻³ m³ (0.001 m³)
→ 1 ml = 0.001 l = 0.000001 m³ = 10⁻⁶ m³

Multiply by 33.69 and you will have 33.69*10⁻⁶ m³
So,the density will be :
ρ = 43.808 g /( 33.69*10⁻⁶)m³
ρ = 43.808*10⁶ / 33.39
ρ = 1.3*10⁶ g/m³
