M = mRT/(pV) . 1) Dumas investigated mercury, finding that at 446°C and 765 torr, 0.812 g of mercury vapor filled a vessel of volume 0.235186 L. From these data, compute the molar mass of mercury.
What is the formula of nitrogen by Dumas method?
0.35g of organic compound contains 28×46.09922,400g of nitrogen. Thus, 100g of compound will contain 28×46.099×10022,400×0.35=16.45 of nitrogen. The percentage of nitrogen in a given organic compound is 16.45%, Option (A).
What is the formula of Vapour density?
It may be defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen. vapour density = mass of n molecules of gas / mass of n molecules of hydrogen. vapour density = molar mass of gas / molar mass of H2 vapour density = molar mass of gas / 2.016 vapour density = 1⁄2 × molar mass.
