Question

A sample of gold has a mass of 38.6 grams and a volume of 2 cm3 what is the density of gold

Answer 1

Answer:

Density, $d=19.3\ g/cm^3$

Explanation:

Mass of the sample of gold, m = 38.6 grams

Volume of gold sample, $V=2\ cm^3$

The density of gold sample is given by mass per unit volume. Mathematically, it is given by :

$d=\dfrac{m}{V}$

$d=\dfrac{38.6\ g}{2\ cm^3}$

$d=19.3\ g/cm^3$

So, the density of the sample of gold is $19.3\ g/cm^3$. Hence, this is the required solution.

Answer 2

Density = Mass ÷ Volume

Your mass = 38.6 grams
Your volume = 2 cm3

38.6 ÷ 2 = 19.3 grams per cm3
