Question

A piece of metal has a mass of 245 mg and a volume of 15.3 mL. What is its density?

A) 16.0 g/ml

B) 0.0160 g/mL

C) 16013 g/mL

D) 3.75 x 10 3 g/mL

Answer 1

Correct option : B) 0.0160 g/mL

-------

Density is mass per unit volume.

Given, the mass of the metal = 245 mg = 0.245 g       ( 1 mg = 0.001 g)

The volume of the metal = 15.3 mL

Density = mass of the metal/volume of the metal

             = 0.245/15.3

             = 0.0160 g/mL
