the density of iron is 7.8 g/cm³. an iron beam has a volume of 10,504 cm³. what is the mass of the iron beam? enter your answer as a decimal in the box.

Answer

Explanation:

Step1: Recall density formula

The density formula is $\rho=\frac{m}{V}$, where $\rho$ is density, $m$ is mass and $V$ is volume. We want to find $m$, so we can re - arrange the formula to $m = \rho\times V$.

Step2: Substitute given values

Given $\rho = 7.8\ g/cm^{3}$ and $V=10504\ cm^{3}$. Then $m=7.8\times10504$. $m = 7.8\times10504=81931.2$ g

Answer:

$81931.2$
