Question

4. The density of gold is 18 g/cm3. If the volume of a plece of gold is 13cm, how many grams will it be?

Answer 1

Therefore there are about 234 grams

Explanation:

We have that the density is given by this formula

`\begin{gathered} d=(m)/(V) \\ \text{where m is the mass and V the volume} \end{gathered}`

We have the value of the density and the volume, therefore we can calculate the number of grams as follows:

`\begin{gathered} 18=(m)/(13) \\ m=18\cdot13 \\ m=234 \end{gathered}`
