Concept explainers

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Solve Part B only

At 700 K acetaldehyde decomposes in the gas
phase to methane and carbon monoxide. The
reaction is:
CH,CHO(g)—CH4(g)+CO(g)
A sample of CH3 CHO is heated to 700 K and
the pressure is measured as 0.39 atm before any
reaction takes place. The kinetics of the reaction
are then followed by measurements of total
pressure and these data are obtained:
