Question

Determine the mass in grams of 25.10 moles of sulfuric acid (H 2 SO 4 ).

Answer 1

Answer : Mass of sulphuric acid, m = ?

Molecular mass of sulphuric acid, M = 1*2 + 32 + 16*4 = 98 u

Number of moles, n = 25.10

By using the formula, n = m / M

› 25.10 = m / 98

› m = 25.10*98

› m = 2459.8 g

› m = 2.4 kg
