The mass of a metal cube is \(5.74 \mathrm{~g}\) and its volume is \(1.2 \mathrm{~cm}^{3}\). Then its density expressed up to appropriate significant figures will be
1 \(4.8 \mathrm{~g} \mathrm{~cm}^{-3}\)
2 \(4.78 \mathrm{~g} \mathrm{~cm}^{-3}\)
3 \(4.783 \mathrm{~g} \mathrm{~cm}^{-3}\)
4 \(5.0 \mathrm{~g} \mathrm{~cm}^{-3}\)
Explanation:
A As we know that, density \(\rho=\frac{\mathrm{m}}{\mathrm{V}}\) Given, \(\mathrm{m}=5.74 \mathrm{~g}, \mathrm{~V}=1.2 \mathrm{~cm}^{3}\) \(\begin{aligned} \therefore \quad \rho =\frac{5.74}{1.2}=4.78333 \mathrm{~g} / \mathrm{cm}^{3} \\ \approx 4.8 \mathrm{~g} / \mathrm{cm}^{3}\end{aligned}\)
