Question

An object of metal has a volume `125cm^3` and density `13.6(gm.)/(cm^3)`, what is its mass in kilograms?

Answer 1

Mass the metal is `1.7` `kg.`

Explanation:

Mass of metal is the product of density and volume. We desire mass in kilograms, but density and volume are given in CGS units. Hence we get mass in grams and

mass is `125xx13.6=1700` grams

Converting it in kilograms, it is `1700/1000=1.7` `kg.`
