sorry im not good at this so i might sound really stupid when i ask this question but , what does that mean then?

anonymous · Answer

you just substitute the value :) you are given a mass of 500 grams and a volume of 8 cc, so to get the denstity you divide the mass by the volume :)

ilovebmth1234 · Answer

62 500 kg / m^3???

anonymous · Answer

no need to convert, answer should be 62.5g/cc. Compare the value with pure gold's density which is 19 g/cc to know if the unknown substance is pure gold or not :)

ilovebmth1234 · Answer

it isn't pure gold because the value is higher than the density of pure gold...
