WitrynaAs we saw in Example 1, there are many different ways to determine the limiting reactant, but they all involve using mole ratios from the balanced chemical equation. The amount of product that can be formed based on the limiting reactant is called the theoretical yield. WitrynaUse the balanced equation to find out the moles of KOH neutralised from HCl. If the ratio is not 1:1, multiply if KOH is greater than HCl in the ratio, divide for the opposite scenario.You should have the moles of KOH and the volume of KOH. Use c = n/V to find the concentration. Again make sure the volume is in dm 3 to get concentration in …
