The limiting reactant is one that produce lower moles of the product and as nicl2 is produing 1 mole of ni,it is limiting reactant. Calculating the amount of product formed from a limiting reactant introduction to gravimetric analysis: Whichever reactant produced a lesser amount of the product is the limiting reactant. The reactant that produces the least amount of product is the limiting reactant.
Remember to use the molar ratio between the limiting reactant and the product.

Ammonia (nh 3) is produced when nitrogen gas (n 2) is combined with hydrogen gas (h 2) by the reaction. If you�re asked to supply a number in grams, you convert back from the moles used in the calculation. Therefore the mass of the limiting reactant was.0045 moles and multiplied by its molar mass of 111g to result in.4995g of the limiting reactant in the salt mixture. Calculate theoretical yield of co 2 first)

Remember to use the molar ratio between the limiting reactant and the product. Find the limiting reactant example. 76/84 =.904 moles 69.8/16 = 4.362 moles 3. You do this by taking the mass given to you of both products and using molar mass and molar ratios to convert into product. Then determine the limiting reactant (using mole ratios from the balanced equation).
