Question

What is the density, with correct number of significant figures, of a sample having a mass of 42.860 grams and a volume of5.78 mL?O 0.13 g/mLO 0.135 g/mL© 7.40 g/mLO 7.42 g/mL

Answer 1

The density is given by:

`\begin{gathered} \rho=(m)/(V) \\ so\colon \\ \rho=(42.860)/(5.78) \\ \rho=(7.42g)/(mL) \end{gathered}`
