(b) A solution of 1.570 grams of the compound in 16.08 grams of camphor is observed to freeze at a temperature 15.2 Celsius degrees below the normal freezing point of pure camphor. Determine the molar mass and apparent molecular formula of the compound. (The molal freezing-point depression constant, Kf, for camphor is 40.0 kg-K-mol¯1.)

This step is the conversion between moles of gas and the volume occupied by 1 mole of gas. For any gas at STP, the molar volume is always 22.41 L/mol. In most cases, however, the gas is not at STP; you then must use the ideal gas law either to find the moles of gas when volume is given or to find the volume once the moles of gas are known.

The solution is said to be a 0.0292 “normal” solution of Ca(OH)2. N can stand for the noun, “normality” or the adjective, “normal”, just as M stands for molarity and molar. Conversion of Normality to Molarity and Molarity to Normality. A problem that comes up frequently is to calculate the normality of a molar …

A normal car will consume petrol at a rate of about ten miles per litre. Although air is heated and pressurised as it enters the car engine, we can assume that the normal molar gas volume applies to the air before it enters. Air is about 20% oxygen. Argon p. roblem. What is the approximate mass of argon in the room you are in at the moment?

Now use the molar heat of vaporization as a conversion. To convert 15.0 g liquid water from 75 °C to 100.°C requires 1600 J, and to convert 15.0 g liquid water at 100.°C to a gas requires 33.8 kJ. To determine the total amount of energy required, we can add together the two quantities of energy.

Molar conductivity is the conducting power of cell the ions produced by one mol of an electrolyte. It is given by = Variation of and with concentration. Conductivity decreases with dilution. Because the number of ions per unit volume that carry the current in a solution decreases. Molar conductivity increases with decrease in concentration.
