1.) What is the mass of 275 mL of mercury knowing that the density of murcury is 13.6g/mc2.) What volume in liters will be occupied by 1.00k of Murcurythat has a density of 13.6 g/mL. 3.) You found a peace of metal. the density of the metal is 7.1g/mL. the mass is 275.7 g How much metal did you find *Show your work*

We can use the following formula in order to solve all the questions:


\begin{gathered} \rho=(m)/(v) \\ \text{where:} \\ \rho=Density \\ m=mass \\ v=volume \end{gathered}

2)


\begin{gathered} v=(m)/(\rho) \\ m=1\operatorname{kg}=1000g \\ \rho=(13.6g)/(ml) \\ v=(1250)/(17)ml\approx73.53ml \end{gathered}

3)


\begin{gathered} v=(m)/(\rho) \\ m=275.7g \\ \rho=(7.1g)/(ml) \\ v=(275.7)/(7.1) \\ v=(2757)/(71)ml\approx38.83ml \end{gathered}
