What is the mass percent of oxygen in Nickel (III) sulfate?

Sagot :

The mass percent of oxygen in Nickel([tex]III[/tex])sulfate is [tex]23.68[/tex] percent.

At first, we look up the atomic masses for the element from the periodic table.

The atomic masses are found to be:

  • Ni is [tex]58.7[/tex]
  • S is [tex]32[/tex]
  • O is [tex]16[/tex]

Next, we determine how many grams of each element are present in one mole of [tex]Ni_{2}(SO_{4})_{3}[/tex]

  • [tex]117.4g(2 mol*58.7)[/tex] of Ni
  • [tex]96g(3 mol*32)[/tex] of S
  • [tex]192g(12 mol * 16.00)[/tex] of O

The mass of one mole  [tex]Ni_{2}(SO_{4})_{3}[/tex] is:

[tex]117.4g+96g+192g=405.4g[/tex]

So, The mass percent of oxygen [tex]=(96g/405.4)*100=0.2368*100%\\[/tex]

                                                    [tex]=23.68 %[/tex] percent.
