The numerical value of the atomic mass of an element or the formula mass in grams expresses that sample contains 1 mole of elements or molecules respectively. Hence there is one mole of N2 in 28 grams of nitrogen, N2.
How many atoms are there in 28 gram of nitrogen gas?
By Avagadro’s law, 1 Nitrogen mole or 28 g of Nitrogen contains 6.023 x 10^23 no. of molecules. Nitrogen, being a diatomic element, the no. of atoms = 2 x 6.023 x 10^23 atoms.

What is the mass of 5 mole of nitrogen?
The mass of given amount of nitrogen atoms is 70 grams.
How many moles are there in 140 gram nitrogen?
Answer. Therefore, number of moles is 5.
How many moles are in 50 grams of nitrogen gas?
We have 50 g of nitrogen gas here, so we need to find the number of moles of nitrogen. From here, we would produce 1.79⋅2=3.58 moles of ammonia.
How do I calculate moles?
- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
How many moles are in 25 grams of HF?
Using this equation, we can take 25/(1.0 + 19) and find that it is equal to 1.25 moles.

How many grams are in 2 moles of N2?
1 Expert Answer
14.01 g/mol is molar mass for Nitrogen (N), thus 28.02 g/mol N2. We start with given, which is 2.20 moles of N2. We then multiply by conversion factor of 28.02 g/mol N2.
How many moles are in H2O?
The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.
