Aluminum has a density of 2.70 g/mL. Calculate the mass (in grams) of a piece of aluminum having a volume of 239 mL .
Answer:
The mass of the piece of aluminum is 645 g.
Explanation:
Density is given by the relationship between mass and volume:
ρ = \(\frac{m}{V}\)
If we take de volume V and pass to multiply the density ρ, we have:
m = ρ V (Equation 1)
with this formula we can find the mass.
We have that ρ = 2.70\(\frac{g}{mL}\) and V = 239mL
So, replacing these values in Equation 1, we can find the value for the mass:
m = 2.70\(\frac{g}{mL}\) 239mL
m = 645 g
