easy

Calculate the molar mass of sulfuric acid (

\text{H}_2\text{SO}_4

). (H = 1.008, S = 32.07, O = 16.00)

1
H: $2 \times 1.008 = 2.016$ . S: $1 \times 32.07 = 32.07$ . O: $4 \times 16.00 = 64.00$ .
2
Total: $2.016 + 32.07 + 64.00 = 98.09\,\text{g/mol}$ .

Answer

M = 98.09\,\text{g/mol}

Sum the atomic masses of all atoms in the chemical formula to find the molar mass.
