Question

Calculate the number of molecules in 200g of nitrogen gas.​

Answer 1

Answer:

Explanation:

2.38 moles

There are 2.38 moles present in a 200-gram sample of sodium bicarbonate with a chemical formula of NaHCO3.

Answer 2

Answer:

Number of moles = weight of substance / molar mass of substance. Therefore, 100 grams of N2 = 100/ 28 moles. Number of molecules of N2 = number of moles x Avogadro number. Since, N2 is diatomic molecule which contain two atoms of nitrogen.
