Consider a mixture of three gases a, b and c at equilibrium. If the individual gas components have pressures equal to Pa, Pb and Pc, determine the total pressure P of the mixture of gases. / (Pa + Pb + Pc) d) P = (Pa x Pb / Pc) + (Pb x Pc / P

Consider a mixture of three gases a, b and c at equilibrium. If the individual gas components have pressures equal to Pa, Pb and Pc, determine the total pressure P of the mixture of gases. / (Pa + Pb + Pc) d) P = (Pa x Pb / Pc) + (Pb x Pc / P Correct Answer P = Pa + Pb + Pc / (Pa + Pb + Pc) d) P = (Pa x Pb / Pc) + (Pb x Pc / P] + (Pc x Pa / P

Dalton’s law of partial pressures states that the total pressure exerted by a mixture of gases is the sum of partial pressures of individual gas components. Hence the answer is P = Pa + Pb + Pc.

A small and medium enterprise imports two components A and B from Taiwan and China respectively and assembles them with other components to form a toy. Components A contributes to 10% of production cost while components B contributes to 20% of production cost. Usually the company sells this toy at 20% above the production cost. Due to increase in the raw material and labour cost in both the countries ,component A became 20% costlier and components B became 40% costlier. Owing to these reasons the company increased its selling price by 15%. Considering that cost of other components does not change. What will be the profit percentage if the toy is sold at the new price?
