rearrange the equation to solve for volume:
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

<u>Explanation:</u>
Scientific notation is the notation where a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....
