What is the percent composition of nio, if a sample of nio with a mass of 41.9 g contains 33.1 g ni and 8.8 g o? show your work.

First, let's calculate the O percent composition:

Let's divide the mass of O by the mass of NiO

8.8 / 41.9 ≈ 0.21

Multiply 0.21 by 100%

0.21 * 100% = 21%

Now, let's calculate the Ni percent composition.

Let's divide the mass of Ni by the mass of NiO.

33.1 / 41.9 ≈ 0.79

Multiply that by 100%

0.79 * 100% = 79%

Thus, the percent composition is 21% Oxygen and 79% Nickel.

Have an awesome day! :)
