For complete combustion of 1 mole of each propane and butane. Find sum of minimum number of moles of O_2 required

Assertion: As mole is the basic chemical unit, the concentration of the dissolved solute is usually specified in terms of number of moles of solute. Reason: The total number of molecules of reactants involved ina balanced chemical equation is known as molecularity of the reaction.
