प्रश्न
What volume of hydrogen sulphide at STP will burn in oxygen to yield 12.8g what volume of oxygen would be required for complete combustion?
उत्तर
From the equation we know that 2 moles of H2S burn in presence of 3 moles of Oxygen so :
44.8L of H2S requires = 67.2L of oxygen
4.48L of H2S will require = 67.2/44.8 x 4.48 = 6.72L
So, 6.72L of oxygen would be required for complete combustion .

A gas is to be filled from a tank of capacity 10,000 litres into cylinders each having capacity of 10 litres. The condition of the gas in the tank is as follows:
- The pressure inside the tank is 800 mm of Hg.
- The temperature inside the tank is −3°C.
When the cylinder is filled, the pressure gauge reads 400 mm of Hg and the temperature is 270 K. Find the number of cylinders required to fill the gas.
