One mole=1000 Milli moles
One mole=6.022 x 1023 molecules of the substance
Therefore, one Milli mole of ammonia has 6.022 x 1023 /103 = 6.022 x 1020 molecules of ammonia.
The chemical equation is N2 + 3H2 -> 2NH3 So reacting 2 moles of N2 will produce 4 moles ammonia.
How many molecules are present in 42.0g of Cl2
12 molecules of carbon 24 of hydrogen 12 of oxygen
5.8 x 10-2 mol
6.022 x 1023 molecules. One mole of any substance has the same i.e. 6.022 x 1023 of its constituents particles.
0,522 moles of ammonia contain 3,143.10e23 molecules of NH3.
There are 6.02x10^23 molecules in one mole of anything.

Ammonia has the chemical formula NH3, and thus there are three hydrogen atoms in a molecule of ammonia.
Each molecule of ammonia has three hydrogen atoms; therefore, 26 molecules of ammonia contain 26 X 3 = 78. However, these hydrogen atoms do not constitute hydrogen molecules, so the literally correct answer is zero.
The number of ammonia molecules is 59 720.10e23.
5.8x10^-2
This is a chemical calculation. there are 0.04166 moles in it.
Gram mole is the mass of a substance which equal to molecular mass in amu. For ammonia we have one nitrogen atom and three atoms of hydrogen. So the molecular mass in amu will be 14+3 = 17 Now 17 g of ammonia would have 6.023 x 1023 molecules. ie avagadro number of molecules. Hence every 1 g will have (6.023/17) x 1023 So for 32 g it would have (32/17) x 6.023 x 1023 molecules.
1 g of ammonia (NH3) is equal to 0,059 mol.
The answer is 0,166.10e23 molecules.
The chemical equation is N2 + 3H2 -> 2NH3 So reacting 2 moles of N2 will produce 4 moles ammonia.
