If Avogadro’s number is A0, the number of sulphur atoms present in 2

1.	If Avogadro’s number is A0, the number of sulphur atoms present in 200 mL of 1N H2SO4 is(A) A0/5(B) A0/2(C) A0/10(D) A0
Answer» Correct option (C) A₀/10 Explanation: M_H2SO4 = 0.5 V_H2SO4 = 0.2 n_H2SO4 = 0.1 no of mole of ‘S’ atom = 0.1 ∴ no of ‘s’ atom = 0.1 A₀ = A₀/10

If Avogadro’s number is A0, the number of sulphur atoms present in 200 mL of 1N H2SO4 is(A) A0/5(B) A0/2(C) A0/10(D) A0

Answer»

Correct option (C) A₀/10

Explanation:

M_H2SO4 = 0.5

V_H2SO4 = 0.2

n_H2SO4 = 0.1

no of mole of ‘S’ atom = 0.1

∴ no of ‘s’ atom = 0.1 A₀

= A₀/10
