To determine how much of the other reactant is left, we have to do one more mass-mass calculation to determine what mass of MgCl2 reacted with the 5.00 g of Rb, and then subtract the amount reacted from the original amount.

NettetSolution. Compute the provided molar amounts of reactants, and then compare these amounts to the balanced equation to identify the limiting reactant. mol Si = 2.00 g Si × 1 mol Si 28.09 g Si = 0.0712 mol Si. mol N 2 = 1.50 g N 2 × 1 mol N 2 28.02 g N 2 = 0.0535 mol N 2. The provided Si:N 2 molar ratio is: Nettet2 dager siden · You can also use the calculator to double-check your work and perform follow-up stoichiometry and limiting reagent calculations. When using online equation balancing apps, be sure to use the proper capitalization for each element. Note that the two methods described earlier to balance equations aren't the only ones. researchgate working paper
