How do I find the molar mass of C18H14N2Na2O8S2 (Alura Red)?
C18H14N2Na2O8S2
Multiply and add.
You can use numbers as accurately as you want the answer but as as estimate it would be
18*12 + 14*1 + 2*14 + 2*23 + 8*16 + 2*32 = ?
There are molar mass calculators on Google.
C = 12
H = 1
N = 14
Na = 23
O = 16
S = 32
so
18*12 + 14*1 + 2*14 + 2*23 + 8*16 + 2*32
Thank you, Dr. Bob and Mr. Damon!
You are welcome.
To find the molar mass of a compound like C18H14N2Na2O8S2 (Alura Red), you need to sum up the atomic masses of each individual element in the compound.
1. Start by writing down the molecular formula of Alura Red: C18H14N2Na2O8S2.
2. Take each element present in the formula (C, H, N, Na, O, S) and identify their respective atomic masses.
- Carbon (C) has an atomic mass of 12.011 g/mol.
- Hydrogen (H) has an atomic mass of 1.008 g/mol.
- Nitrogen (N) has an atomic mass of 14.007 g/mol.
- Sodium (Na) has an atomic mass of 22.990 g/mol.
- Oxygen (O) has an atomic mass of 15.999 g/mol.
- Sulfur (S) has an atomic mass of 32.06 g/mol.
3. Multiply the number of atoms for each element by their respective atomic masses, and then sum them up.
- Carbon: 18 atoms x 12.011 g/mol = 216.198 g/mol
- Hydrogen: 14 atoms x 1.008 g/mol = 14.112 g/mol
- Nitrogen: 2 atoms x 14.007 g/mol = 28.014 g/mol
- Sodium: 2 atoms x 22.990 g/mol = 45.98 g/mol
- Oxygen: 8 atoms x 15.999 g/mol = 127.992 g/mol
- Sulfur: 2 atoms x 32.06 g/mol = 64.12 g/mol
4. Add up all the atomic masses: 216.198 + 14.112 + 28.014 + 45.98 + 127.992 + 64.12 = 496.416 g/mol.
Therefore, the molar mass of C18H14N2Na2O8S2 (Alura Red) is approximately 496.416 grams per mole (g/mol).
