Question

Weight of a body is 6.34 g and its volume is 1.7 cm? What will be the
density of substance?​

Answer 1

Explanation:

Since,

$weight \: = mass \: \times gravity \\ that \: is \\ w \: = mg \\ therefore \: \\ m = \frac{w}{g} = \frac{0.00634}{9.8} \\ = 0.000647 \: kg \\ = 0.647 \: gm\\ density \: = \frac{mass}{volume} \\ = \frac{0.647}{1.7} = 0.3805 \: g \: per \: {cm}^{3}$
