Question

the weight of H2 S o4 is in 1200 ml of the solution of 0.2 and strength will be​

Answer 1

Answer:

volume = 1200ml

mass = m = ?

number of hydrogen ions = n = 2

equivalent mass = molar mass of solute/n

E.M = 2+32+64/2

E.M = 98/2

E.M = 49 g

Normality = mass of solute × 1000 /equivalent mass of solute × volume (in ml)

N = m × 1000/E.M × 1200ml

m = N×E.M×1200/1000

m = 0.2×49×1200/1000

m = 9.8×1.2

m = 11.76 g .
