Problem

The mass of piece of paper is 0.02 g and the mass of a solid substance along with the same piece of paper is 20.036 g. If the volume of the solid is

2.16 \text{ cm}^3

, its density to the proper number of significant digits will be

9.3 \text{ g cm}^{-3}

9.34 \text{ g cm}^{-3}

9.27 \text{ g cm}^{-3}

43.24 \text{ cm}^{-3}

(1)

9.3 \text{ g cm}^{-3}

(2)

9.34 \text{ g cm}^{-3}

(3)

9.27 \text{ g cm}^{-3}

(4)

43.24 \text{ cm}^{-3}
