Question

What is the mass of 32.1 mL the density of copper is 8.96 g/mL

Answer 1

288 g.

Step-by-step explanation:

Measurements => Density.

Density is the ratio of the mass of an object to its volume:

`D=(m)/(V),`

where D is density, m is mass, and V is volume.

We have two data: the volume (32.1 mL) and the density (8.96 g/mL) and we need to find the mass.

We can solve for 'm' in the given equation and replace the given data, as follows:

`\begin{gathered} m=D\cdot V, \\ \\ m=8.96(g)/(mL)\cdot32.1\text{ mL,} \\ \\ m=287.6\text{ g}\approx288\text{ g.} \end{gathered}`

The answer would be that the mass is 288 g.
