# Calculating Volume And Scientific Notation?

i need to make sure what i'm doing is right and if not where i'm going wrong. The question is;

The planet Jupiter has a mass of 1.899 × 10^27 kg

and a density of 1.24 × 10^3 kg m–3.

Use this information to calculate the volume of Jupiter.

You should give your answer in scientific notation to the appropriate number of significant figures and with the correct SI units.

I know volume = mass/density (correct me if i'm wrong) so on my calculator i put in 1.899 × 10^27 / 1.24 x 10^3 which equals a really horrible number. It equals;

1531451612903225806451612903225.8

This answer does not seem right, what do i do from here? and whats the answer?

You have too many digits on the LHS of the decimal point. When dividing the numbers you used you will get 1.53145E+24 ~ 1.53 x 10*24 in scinot. Your decimal notation should have 25 digits to the left of the decimal point; I think you have more. Where they came from, I've no clue unless you put in 10^-3 instead of 10^3 for the bottom number. But the abscissa seems correct.

I agree with your first answer that 1.53 x 10^24 is the right number. Your question asks for the answer in scientific notation, so your answer should be

1.53 x 10^24 m^-3
