How do you determine the maximum amount of product that can be formed?

Limiting-reactant principle – The maximum amount of product possible from a reaction is determined by the amount of reactant present in the least amount, based on its reaction coefficient and molecular weight.

How do you find the number of moles in a product?

In order to calculate the moles of a product, you must know the mass of the product, and its molar mass (g/mol), which is the mass of one mole of of the product. You then divide the mass of the product by its molar mass.

How do you find the moles of a product of a limiting reactant?

Use mole ratios to calculate the number of moles of product that can be formed from the limiting reactant. Multiply the number of moles of the product by its molar mass to obtain the corresponding mass of product.

How do you find the moles of products given moles of reactants?

Calculate the limiting reactant, or the reactant which will run out first, by setting up the first of two equations. In this first equation, choose one of the reactants and multiply the moles of that reactant by the ratio of moles of reactant to moles of product.

How do you calculate the number of moles needed to react?

Determine the number of moles needed to react by multiplying by moles of the known substance by the stoichiometric ratio of the unknown substance to the known substance.

How many grams of AlCl3 will be produced if 2.5 moles of Al react?

How many grams of AlCl3 will be produced if 2.50 moles of Al react? The coefficients before Al and AlCl3 are equal, so from 2.50 moles of Al 2.50 moles of AlCl3 are obtained. m(AlCl3)=2.50*133.5=333.75(g).

What is the mole ratio of HCl to AlCl3?

What mass of hydrochloric acid is generated by 2kg of aluminium chloride and what mass of aluminium hydroxide is precipitated? From Equation 4.11, 1 mole of AlCl3 generates 3 moles of HCl and 1 mole of Al(OH)3.
