Question

The density of brass is about 8.5 g/mL. How much mass would an object, that is made of brass and is 2 mL have?

How about an object that is made of brass, but has a volume of 0.5 mL?

Answer 1

The mass of the object of 2ml is 17g

The mass of the objects of 0.5ml is 4.25g

Explanation:

Let the mass be 'm'

Density= 8.5 g/ml

Volume = 2ml

Density= mass/ volume

8.5 = m / 2

m = 8.5 x 2

m = 17g

The mass of the object of 2ml is 17g

Volume = 0.5ml

Density= 8.5 g/ml

Density= mass/ volume

8.5 = m / 0.5

m = 8.5 x 0.5

m = 4.25 g

The mass of the objects of 0.5ml is 4.25g
