Question
Chapter 6, Problem 40E
Interpretation Introduction
Interpretation:
To interpret the molar mass of acetylene and the conclusion about the molecular formula of the compound should be explained.
Concept introduction:
The pressure (P), volume (V) and temperature (T) of any gas are related to number of moles of gases with an ideal gas equation.
The mathematical expression for ideal gas is:
Here, R represents the Universal gas constant and n is number of moles of gas.
The molecular formula of any compound can be calculated with the help of mass percentage which gives the empirical formula that is directly related to molecular formula.
