Moles of ammonium sulfide = 5.80 mol
The formula of ammonium sulfide is (NH₄)₂S
So each molecule of ammonium sulfide has (4 x 2) or 8 atoms of H
One mole of ammonium sulfide has 8 moles of H
5.80 mol of ammonium sulfide has (8 x 5.8) or 46.4 moles of H
As per the definition of Avogadro's number, 1 mole = 6.022 x 10²³ atoms
46.4 moles of H x (6.022 x 10²³ atoms/ 1 mole of H)
= 2.8 x 10²⁵ H atoms
Therefore, 2.8 x 10²⁵ H atoms are in 5.80 mol of ammonium sulfide.
Answer:
A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.5 kPa.
<u>The pressure for oxygen is 3 kPa</u>
Explanation:
According to Dalton's Law of Partial Pressure total exerted by the mixture of non-reacting gases is equal to sum of the partial pressure of each gas.
So,
For , a gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure:
Insert the values in :
Answer: 150N
Explanation:
The formula to calculate the force will be the mass multiplied by the acceleration. In this case, mass = 15kg and acceleration = 10m/s². Therefore, force will be:
= Mass × Acceleration
= 15 × 10
= 150N
The force is 150Newton
We don't know what statement you want us to choose from. But, protons have a positive charge, and they are what makes an atom a certain atom.
