A 5.00 cm^3 sample of gold has a mass of 96.5 g. Calculate the density of gold.

Sholpan [36]

Answer:

$\boxed {\boxed {\sf 19.3 \ g/cm^3}}$

Explanation:

We are asked to calculate the density of gold. The density of a substance is its mass per unit volume. It is calculated using the following formula.

$\rho= \frac{m}{v}$

The mass of the sample is 96.5 grams. The volume of the sample is 5.00 cubic centimeters.

m= 96.5 g
v= 5.00 cm³

Substitute the values into the formula.

$\rho= \frac{ 96.5 \ g}{5.00 \ cm^3}$

Divide.

$\rho= 19.3 \ g/cm^3$

The density of gold is <u>19.3 grams per cubic centimeter.</u>
