Interpretation: The minimum amount of hydrogen gas in grams is to be calculated.
Concept Introduction: Hydrogenation reaction is the
The general form of hydrogenation reaction is:
R=R+H2→ R−RAlkene Hydrogen Alkane
To determine the mass of the second reactant from the given mass of first reactant, follow the following solution map:
given mass of first reactant→usingmolar massas aconversionfactormoles of first reactant →By using conversion factor moles of second reactant →usingmolar massas aconversionfactormass of second reactant
The conversion factor used to convert the moles of first reactant into the moles of second reactant is basically the stoichiometric relationship between moles of reactant and moles of product. The conversion factor is obtained from the balanced chemical equation. The mass of the second reactant is converted into their corresponding moles by the use of their corresponding molar masses.
