367.5 gm `KClO_(3)` (M = 122.5) when heated, How many litre of oxygen gas is proudced at S.T.P.

5.6 litre of oxygen at S.T.P

5.6 litres of oxygen at STP is equivalent to

A m^(3) vessel at STP has oxygen gas. How many moles of oxygen are present?

Calculate the amount of potassium chlorate (KClO_(3)) which must be heated to produce 2.4 litres of oxygen at 740 mm Hg and at 25^(@)C .

Calculate the amount of potassium chlorate (KClO_(3)) which must be heated to produce 2.4 litres of oxygen at 740 mm Hg and at 25^(@)C .

The heat of combustion of ethane gas is 373 K Cal per mole. Assuming that 50% of heat is lost, how many litres of ethane measured at S.T.P. must be burnt to convert 50 kg of water at 10^@C to steam at 100^@C ? One mole of gas occupies 22.4 litres at S.T.P. Latent heat (L) of steam = 2.25 xx 10^6 J k^-1 .

Ammonia is oxidised according to equation : 4NH_(3)+5O_(2)to4NO+6H_(2)O How many litres of NO are formed when 90 litres of oxygen react with ammonia at S.T.P.?
