Question

Please help thank you! And how many significant figures does it have?

Answer 1

Answer:

0.779 cube centimetres

Explanation:

density = mass divided by volume

$d=\frac{m}{v}$ rearrange the equation to solve for volume: $v=\frac{m}{d}$

plug in the corresponding values:

volume = 6.130 g / 7.87 (gcm^3)

the gs cancel, the answer will be 0.7789

we will round to three sig figs, since that's the lowest amount of figures in the given values: ~0.779 cm^3
