Question: Calculate these masses

a) What is the mass of 6.00 cm3 of mercury, density = 13.5939 g/cm3?

b) What is the mass of 25.0 mL octane, density = 0.702 g/cm3?

Short Answer

Expert verified

a) Mass of mercury = 81.6 g

b) Mass of octane = 17.6 g

Step by step solution

01

To determine the mass of mercury

\(\begin{array}{l}Density = \frac{{mass}}{{volume}}\\mass = density \times volume\\mass = 6.00c{m^3} \times 13.5939g/c{m^3}\\mass = 81.6g\end{array}\)

02

To determine the mass of octane

\(\begin{array}{l}mass = density \times volume\\mass = 25.0mL \times \frac{{1c{m^3}}}{{1mL}} \times 0.702g/c{m^3}\\mass = 17.6g\end{array}\)
