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.

Respuesta :

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! :)

The percentage composition of oxygen and nickel in the NiO is 21% and 79% respectively.

What is percentage composition?

The relative mass of the constituent atoms in the given amount of compound is called percentage composition.

First, calculate the mass percent of Oxygen:

[tex]M_O = \dfrac {8.8} {41.9 }\times 100\\\\M_O = 0.21\%[/tex]

Now calculate the mass percentage of Nickle,

[tex]M_N_i = \dfrac {33.1} {41.9 }\times 100\\\\M_N_i = 79\%[/tex]

Therefore, the percentage composition of oxygen and nickel in the NiO is 21 % and 79% respectively.
