Question

A gold bar has a volume of 4.7 cm3 and a density of 19.3 g/ cm3. What is its mass?

Answer 1

Mass of the gold bar is 90.71 gram.

Step-by-step explanation:

Given:

volume = 4.7
`cm^(3)`

density = 19.3
`(g)/(cm^(3))`

To find:

mass = ?

Formula used:

density =
`(mass)/(volume)`

Solution:

density is given by,

density =
`(mass)/(volume)`

mass = volume × density

mass = 4.7 × 19.3

mass = 90.71 g

Mass of the gold bar is 90.71 gram.
