Question

aluminum has a density of 2.70 g/ml. calculate the mass (in grams) of a piece of aluminum having a volume of 250 ml .

Answer 1

density = 2.70 g/mL

Volume = 250 mL

D = m / V

2.70 = m / 250

m = 2.70 x 250

m = 675 g

hope this helps!

Answer 2

Answer: The mass of aluminium is 675 g

Step-by-step explanation:

To calculate volume of a substance, we use the equation:

`\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}`

We are given:

Density of aluminium = 2.70 g/mL

Volume of aluminium = 250 mL

Putting values in above equation, we get:

`2.70g/mL=\frac{\text{Mass of aluminium}}{250mL}\\\\\text{Mass of aluminium}=16.2mL`

Hence, the mass of aluminium is 675 g
