We are familiar with the pressure (P), volume (V), temperature (T), and number of moles (n) of gas in the Ideal Gas Law equation but the molar mass of the gas can also be calculated from the same equation. Like any other calculations with the molar mass...

When heat capacity is given in terms of the mass of a substance in grams it is called specific heat—the amount of heat required to raise the temperature of 1 g of a substance by 1 Celsius degree. (We choose to use units with specific heat, as many do, because it is desirable in ...
