| January 28, 2021 | education
To calculate the molar mass of a substance, you need to sum up the atomic masses of all elements, while multiplying by the index that stands near the element and indicates its amount.
M (H2SO4) = 2 * Ar (H) + Ar (S) + 4 * Ar (O);
M (H2SO4) = 2 * 1 + 32 + 4 * 16 = 98 (g / mol);
Answer: the molar mass of sulfate acid is 98 g / mol.
