प्रश्न
If 112 cm3 of hydrogen sulphide is mixed with 120 cm3 of chlorine at STP, what is the mass of sulphur formed?
H2S + Cl2 → 2HCI + S
उत्तर
At STP, 22400cm3 of each H2S and Cl2 will give 32g of sulphur i.e.
44800 cm3 of H2S + Cl2 gives = 32g of S
(112 +120) = 232cm3 of H2S + Cl2 will give = 32 x 232 / 44800 = 0.16g of S
