Understanding the Molecular Weight of Sulfuric Acid

The molecular weight of a compound is the sum of the atomic weights of all the atoms in its molecular formula. For sulfuric acid, the molecular formula is H2SO4. This means it consists of two hydrogen atoms, one sulfur atom, and four oxygen atoms. To calculate the mol wt of H2SO4, we need to sum the atomic weights of these elements:

Hydrogen (H): 1.008 amu
Sulfur (S): 32.065 amu
Oxygen (O): 15.999 amu

Using these values, the calculation for the mol wt of H2SO4 is as follows:

Mol Wt of H2SO4 = (2 x 1.008 amu) + (1 x 32.065 amu) + (4 x 15.999 amu)

Mol Wt of H2SO4 = 2.016 amu + 32.065 amu + 63.996 amu

Mol Wt of H2SO4 = 98.077 amu

Therefore, the mol wt of H2SO4 is approximately 98.077 amu (atomic mass units).
