Stoichiometry
1 kg of calcium carbide (CaC₂) produces about 0.41 kg of acetylene gas on treatment with water. How many hours of service can be derived from 1 kg of calcium carbide in an acetylene lamp burning 35 litres of gas at NTP per hour?
Attractive forces between like and unlike molecules are approximately equal
Sizes of the component molecules are approximately equal
Component molecules are non-polar and no chemical combination or molecular association between unlike molecules takes place in the formation of the solution
