Question

0.6717g divided by 3.99cm cubed

Answer 1

0.1683 g/cm^-3    {grams per centriemtre cubed}

Answer 2

0.6717g divided by 3.99cm cubed:

0.6717g / 63.521199cm = 0.010574422564033 g/cm, but centimeters cubed are also ML (millileters)- therefore your answer is 0.16834 g/mL.

(you may want to round this off to something, depending on if your question specifies what to round it to. (tenths, hundredths, etc.)

Answer 3

This is to figure out density (cm^3 is the same as mL)

so, heres the math :P

0.6717/3.99=0.16834 g/mL

however, due to the rules of significant digits, you only use as many sig digs as you there are in the number with the lowest amount of them (i.e. 3.99) so the answer is really 0.168 (or 1.69 x 10^1) g/mL
