From the question, we are provided with the mass percentage of carbon in a hydrocarbon, mass percentage of hydrogen, volume of gas, pressure, and we convert the pressure of mm into hg.
00:22
The value of pressure in atmospheric will be 0 .715 atmospheric pressure.
00:29
And we are provided with the temperature in celsius, converting into, into kelvin we have temperature of 298 kelvin along with that we have the mass of the gas let us assume that there are 100 grams of hydrocarbon then the mass of carbon hydrogen would be 82 .66 and 17 .34 grams respectively therefore the falling table predicts the empirical formula of a compound as c2h5.
01:11
From the ideal gas equation, the molar mass of a gas will be, the molar mass will be weight multiplied with the gas constant, multiplied with temperature, divided by pressure, multiplied with volume.
01:33
Substituting in the values, we have 0 .275, multiplied with 0 .0 .08, multiplied with temperature of 298 divided by 0 .715 and 0 .158...
