# The density of lead is 11.3 g/mL. What is the mass of 45 mL of the metal?

Jun 8, 2018

508.5 g

#### Explanation:

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

$\rho \cdot v = m$

$11.3 \frac{g}{m L} \cdot 45 m L = 508.5 g$

$\text{Mass} = 508.5 g$

#### Explanation:

$\text{Density" = "Mass"/"Volume}$

$\text{Mass" = "Density" xx "Volume}$

Given;

$\text{Density} = \frac{11.3 g}{m L}$

$\text{Mass} = 45 m L$

Plugging in the values..

$\text{Mass} = \frac{11.3 g}{\cancel{m L}} \times 45 \cancel{m L}$

$\text{Mass} = 11.3 g \times 45$

$\text{Mass} = 508.5 g$
