What is the molar mass of salenH(2) and nickel(II) salen?
I don't know shat salen is? Do you have a formula?
Salen is a contraction for salicylic aldehyde and ethylene diamine which are the reactants for the basic ligand. There are a number of these so you will need find out which one you have got.
Salicylalhyde is HO(C6H4)CHO and two of these react with one molecule of NH2CH2CH2NH2 to give Salen and two molecules of water.
To calculate the molar mass of salenH(2), we need to determine the molar masses of each component and add them together.
1. For salicylaldehyde (HO(C6H4)CHO), we can break down the formula and calculate the molar mass:
- Mass of H: 1.01 g/mol x 1 = 1.01 g/mol
- Mass of O: 16.00 g/mol x 1 = 16.00 g/mol
- Mass of C: 12.01 g/mol x 8 = 96.08 g/mol
- Total molar mass of salicylaldehyde = 1.01 g/mol + 16.00 g/mol + 96.08 g/mol = 113.09 g/mol
2. For ethylenediamine (NH2CH2CH2NH2):
- Mass of H: 1.01 g/mol x 6 = 6.06 g/mol
- Mass of N: 14.01 g/mol x 2 = 28.02 g/mol
- Total molar mass of ethylenediamine = 6.06 g/mol + 28.02 g/mol = 34.08 g/mol
3. To calculate the molar mass of salenH(2), we add the molar masses of salicylaldehyde and ethylenediamine:
- Total molar mass of salenH(2) = 113.09 g/mol + 34.08 g/mol = 147.17 g/mol
For nickel(II) salen, we need to consider the molar mass of salen and the molar mass of nickel (Ni).
4. The molar mass of nickel (Ni) is found on the periodic table and is approximately 58.69 g/mol.
5. To calculate the molar mass of nickel(II) salen, we add the molar masses of salen and nickel:
- Total molar mass of nickel(II) salen = 147.17 g/mol + 58.69 g/mol = 205.86 g/mol
Therefore, the molar mass of salenH(2) is 147.17 g/mol and the molar mass of nickel(II) salen is 205.86 g/mol.
