SUMMARY

The reaction X + 5Y > 3Z involves 3 moles of X and 2.8 moles of Y. To determine how much X will react, one must identify the limiting reactant. Given the stoichiometry of the reaction, 5 moles of Y are required for every mole of X. Since 2.8 moles of Y are available, Y is the limiting reactant, which will dictate the amount of X that reacts. Therefore, only 0.56 moles of X will react, as calculated from the stoichiometric ratios.

PREREQUISITES
  • Understanding of stoichiometry in chemical reactions
  • Knowledge of limiting reactants and excess reactants
  • Basic algebra for calculating mole ratios
  • Familiarity with chemical reaction equations
NEXT STEPS
  • Study stoichiometric calculations in chemical reactions
  • Learn about limiting and excess reactants in detail
  • Practice with various chemical reaction problems
  • Explore the concept of mole ratios in different types of reactions
USEFUL FOR

Chemistry students, educators, and anyone involved in chemical engineering or reaction analysis will benefit from this discussion.

I think its 1 mole but not sure.
 
This is merely a stoiciometry exercise, somewhat generalized. Find which reactant is the limiting reactant; that determines how much of the other reactant will be consumed.

The written reaction shows 1 mole of X; the situation uses 3 moles of X.
The written reaction shows 5 moles of Y; the situation uses 2.8 moles of Y.
Either X or Y is likely to be in excess. Which one? The other is then the limiting reactant.
