I think there are 2.20 * 6.023 * 1023 molecules. i.e, 13.2506 * 1023 molecules
To find the number of moles of N in N2O, we need to use the molar mass of N2O. The molar mass of N2O is 44.02 g/mol. First, calculate the moles of N2O: 0.189g / 44.02 g/mol = 0.0043 moles of N2O Since each N2O molecule contains 2 nitrogen atoms, the number of moles of N is: 0.0043 moles * 2 = 0.0086 moles of N.
First, calculate the number of moles of NaOH: Moles = Molarity x Volume (L) Convert mL to L: 450 mL = 0.45 L Moles = 0.25 N x 0.45 L = 0.1125 moles of NaOH.
To find the number of moles in a sample, divide the mass of the sample by the molar mass of the substance. The molar mass of nitrogen is approximately 14 g/mol. Therefore, in a 78.56 g sample of nitrogen, there are 78.56 g / 14 g/mol ≈ 5.611 moles of nitrogen.
To find the grams of nitrogen (N) in 34.0g of N2O, you need to consider the molar mass of N2O (44.02 g/mol) where 28.02 g out of 44.02 g is nitrogen. Therefore, in 34.0g of N2O, there are 34.0g * (28.02g/44.02g) = 21.6g of N.
[ 217(g) / 44.013(g/mol) ] * 2(molN/molN2O) = 9.86 mol NDivide mass (g) by molar mass (g/mol) to get moles of N2O, this should be multiplied by 2 for the stoechiometric factor of atoms N per molecule N2O.
The answer is 0,0043 moles of N2.
One molecule of N2O N 2 O contains one atom of oxygen.
There are 0.003659 N2O moles. So there are o.007318 moles of N.
n is the number of moles.
There is no nitrogen in water.
3 x 12 = 36 moles of Nitrogen atoms N or 18 moles of Nitrogen molecules N2
n is number of moles per unit length and N is number of moles.
To find the number of moles of N in N2O, we need to use the molar mass of N2O. The molar mass of N2O is 44.02 g/mol.

3,44 moles H2 react with 1,146 moles NH3. The limiting reactant is hydrogen. O,244 moles N2 remain. 19,5 g NH3 are obtained.
First, calculate the number of moles of NaOH: Moles = Molarity x Volume (L) Convert mL to L: 450 mL = 0.45 L Moles = 0.25 N x 0.45 L = 0.1125 moles of NaOH.
