Calculate the molar mass in any SO2 & caffeine (C8H10N4O2) ??

The molar mass of any compound is calculated by summing up the atomic masses of all the atoms in the compound.

For SO2:
Sulfur (S) has an atomic mass of 32.07 g/mol.
Oxygen (O) has an atomic mass of 16.00 g/mol.

Molar mass of SO2 = (1 * S) + (2 * O)
= (1 * 32.07 g/mol) + (2 * 16.00 g/mol)
= 32.07 g/mol + 32.00 g/mol
= 64.07 g/mol

For caffeine (C8H10N4O2):
Carbon (C) has an atomic mass of 12.01 g/mol.
Hydrogen (H) has an atomic mass of 1.01 g/mol.
Nitrogen (N) has an atomic mass of 14.01 g/mol.
Oxygen (O) has an atomic mass of 16.00 g/mol.

Molar mass of caffeine = (8 * C) + (10 * H) + (4 * N) + (2 * O)
= (8 * 12.01 g/mol) + (10 * 1.01 g/mol) + (4 * 14.01 g/mol) + (2 * 16.00 g/mol)
= 96.08 g/mol + 10.10 g/mol + 56.04 g/mol + 32.00 g/mol
= 194.22 g/mol

Therefore, the molar mass of SO2 is 64.07 g/mol and the molar mass of caffeine (C8H10N4O2) is 194.22 g/mol.
