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

Answer:

Mass of the gold bar is 90.71 gram.

Explanation:

Given:

volume = 4.7 $cm^{3}$

density = 19.3 $\frac{g}{cm^{3}}$

To find:

mass = ?

Formula used:

density = $\frac{mass}{volume}$

Solution:

density is given by,

density = $\frac{mass}{volume}$

mass = volume × density

mass = 4.7 × 19.3

mass = 90.71 g

Mass of the gold bar is 90.71 gram.
