You add 9.3g of iron to 26.60mL of water and observe that the volume of iron and water together is 27.78mL . Calculate the density of iron

ok so how do you find the density

9.3 grams of iron made the volume increase to 27.78
dan815
  • dan815
so 27.78 - 26.60=volume of the 9.3g can you figure it out from here?
toxicsugar22
  • toxicsugar22
not really as I am new to this and not familar with this density problem
toxicsugar22
  • toxicsugar22
can you tell me step by step
toxicsugar22
  • toxicsugar22
please
dan815
  • dan815
alright
dan815
  • dan815
so remember desity = mass / volume
dan815
  • dan815
we already given the mass or the weigh of this chunk of iron
dan815
  • dan815
but we dont know the size(or volume) of that iron
dan815
  • dan815
but we can get the volume of that iron by simply seeing how much water it displaces
dan815
  • dan815
the water level rises a certain volume, because that volume is taken up by the little iron piece now
dan815
  • dan815
so if the water went from 26.60ml to 27.78 ml, the reason it changed that ammount of volmue is because an iron piece of that volume difference was placed in there that means the iron piece has volume 27.78ml - 26.60 ml = ?
dan815
  • dan815
1.18 ml...
dan815
  • dan815
now we has the mass of the iron and its volume so density = mass/volume =9.3g/1.18ml =?
toxicsugar22
  • toxicsugar22
is it 7.88
dan815
  • dan815
xD i kinda gave you the answer lol
dan815
  • dan815
i hope you understand this stuff though
dan815
  • dan815
nothing too hard, just remember density = mass / volume
toxicsugar22
  • toxicsugar22
ok
toxicsugar22
  • toxicsugar22
thansk
toxicsugar22
  • toxicsugar22
it is in ml, the units
dan815
  • dan815
no its what it is
dan815
  • dan815
=9.3g/1.18ml We got grams dividing ml... so g/ml

  • toxicsugar22
ooh
