Question

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

Answer 1

The mass percent of oxygen in Nickel($III$)sulfate is $23.68$ 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 $58.7$
• S is $32$
• O is $16$

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

• $117.4g(2 mol*58.7)$ of Ni
• $96g(3 mol*32)$ of S
• $192g(12 mol * 16.00)$ of O

The mass of one mole  $Ni_{2}(SO_{4})_{3}$ is:

$117.4g+96g+192g=405.4g$

So, The mass percent of oxygen $=(96g/405.4)*100=0.2368*100%$

                                                    $=23.68 %$ percent.
