  1. Hello all, I have had help on this forum before and it was very informative but I have been presented with a calculation I am not entirely sure how to work out so am looking for some help again please. The question is shown below along with the answer I believed to have been correct. I understand the equation is V=M/P however I believe the bit that threw me off was the fact that the density has 2 powers, one in the sum 1.24x103 and one again in the unit m-3 I would be very grateful if somebody could break down how to work this out so I could give it another go. I just realised some people may not be able to zoom in to see the image I uploaded … so, the question is: The planet Jupiter has a mass of 1.899 × 1027 kg and a density of 1.24 × 103 kg m–3.Use this information to calculate the volume of Jupiter My incorrect answer was: 2.354 x 1030 kg m-3
  2. Thank you guys all for the help, I got the answer correct after reading all your replies... I didn't realise it could be so easy as to divide the full numbers then just subtract the powers and write that in a scientific fomat. Thank you again all for the help.
  3. Hello, as my username suggests... I am new to science and I am studying online so it is a bit harder to get help with my questions. I have answered the following sum but I have 3 possible answers (probably wrong) so i just want to confirm how to actually work this out properly to see if any of my answers are correct. Also how should I properly display the answer if asked to "give your answer in scientific notation and without any brackets" does this mean show my answer as a sum such as this: A x 10 to the power of B? (not sure how to write in small nexto the 10 to shower the power properly but I'm sure you understand what I mean above)
