Question

An iron bar has volume 650 cm' and density 7.87 g/cm3.

Work out the mass of the iron. Give your answer in
a) grams
b) kilograms​

Answer 1

a.5115.5g

b. 5115.5/1000= 5.1kg

Explanation:

Given data

volume= 650 cm^3

density= 7.87 g/cm^3

We know that

density= mass/volume

mass= density*volume

mass= 7.87*650

mass= 5115.5 g

a.5115.5g

b. 5115.5/1000= 5.1kg
