A piece of metal has a mass of 2210 g. The volume of the metal is 260 cm³.
Vlada [557]

Answer:

density= 8.5\,\,\frac{g}{cm^3}

Step-by-step explanation:

Recall that the formula for density is:

density=\frac{mass}{volume}

therefore for this case we have:

density=\frac{mass}{volume} \\density=\frac{2210}{260} \,\frac{g}{cm^3} \\density= 8.5\,\,\frac{g}{cm^3}
