Chemistry Honors:
Calculations Involving a Limiting Reactant
For each of the following unbalanced chemical equations, suppose that exactly 5.00 g of each reactant is taken. Determine which reactant is limiting, and calculate what mass of each product is expected (assuming that the limiting reactant is completely consumed).
S(s) + 2H2SO4(aq) -- 3SO2(g) + 2H2O(l)

anonymous · Answer

how do you calculate the limiting reactant  with 2 moles h2so4

jfraser · Answer

the balanced reaction tells you the mole ratio of the reactants that are required, but you're given MASS.

turn the 2 masses into moles of each, then compare to the mole ratio from the reaction.
