Mass and Density query?

[carl1]

Hi all, my daughter hsa been asked to solve the following

 

The planet Neptune has a mass of 1.028 × 1026 kg and a density of 1.61 × 103 kg m–3. Use this information to calculate the volume of Neptune. Volume, , is given by

m

volume= ---

p

 

 

where (m) is mass and (p) is density.

 

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

 

Many thanks carl1

well you have everything you need just plug in the mass where there is the m and the density where there is the p(its actually the greek letter rho) and there's your answer.

you also need to know the significant figure rules and how to use scientific notation

the top half (or so) of this page should be useful. If you have any difficulties, just ask for further clarification.
