We know that the formula to calculate the molarity of a substance is M = n/V (n = moles, and V = volume of the solution).

How do you calculate phosphate?

Since the PO4 molecule is three times as heavy as the P atom, results reported as PO4 are three times the concentration of those reported as P. For example, if you measure 0.06 mg/L as PO4, that's equivalent to 0.02 mg/L as P. To convert PO4 to P, divide by 3. To convert P to PO4, multiply by 3.

How do you calculate stoichiometry?

Flowchart of steps in stoichiometric calculations. Step 1: grams of A is converted to moles by multiplying by the inverse of the molar mass. Step 2: moles of A is converted to moles of B by multiplying by the molar ratio. Step 3: moles of B is converted to grams of B by the molar mass.

What is the formula used to calculate the number of moles in a given sample?

Answer: To calculate the number of moles present in a solution, take the molarity of the solution and multiply it with the volume of the solution (in liters). This gives the number of moles present in the solution.

How do you find the complete reaction in chemistry?

A reaction is "completed" when it has reached equilibrium — that is, when concentrations of the reactants and products are no longer changing. If the equilibrium constant is quite large, then the answer reduces to a simpler form: the reaction is completed when the concentration of a reactant falls to zero.
