How do you calculate molar mass?

The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

How to find molarity?

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 find the molar mass of an unknown compound?

Multiply the atomic weight (from the periodic table) of each element by the number of atoms of that element present in the compound. 3. Add it all together and put units of grams/mole after the number. For many (but not all) problems, you can simply round the atomic weights and the molar mass to the nearest 0.1 g/mole.

How do you make 0.5 M sodium phosphate?

Prepare sodium phosphate dibasic stock (0.5 M) by dissolving 35.5 g of sodium phosphate dibasic in a final volume of 500 mL of H2O. Some crystallization will occur when the solution is stored at 4ºC. Warm on a hot plate and stir until the crystals dissolve.

How do you make 0.01 M sodium phosphate?

Dissolve ingredients in distilled water and bring volume to 1 liter. Dilute stock solution 1+9 in double distilled water. Mix well. Adjust pH to 7.5 with 0.1 N HCl or 0.1 N NaOH if necessary.

What is sodium per phosphate?

Sodium phosphate is in a class of medications called saline laxatives. It works by causing diarrhea so that the stool can be emptied from the colon.

How do you find the mass of a product in a chemical reaction?

1) Make sure the chemical equation is balanced! 2) Determine which reactant is the limiting reagent . 3) Use the limiting reactant to convert from moles of reactants to moles of products. 4) Use the molar mass to convert the moles of product to mass.

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.

What is another name for sodium phosphate?

What is Sodium Phosphate? Sodium phosphate also known as phospho soda with the formula Na3PO4 is a saline cathartic that is familiar to radiologists since it is often used as a cleansing agent prior to double contrast barium enema.

How do you calculate sodium phosphate buffer?

The requirement is for a 0.1 M Na-phosphate buffer, pH 7.6. In the Henderson-Hasselbalch equation, pH = pKa + log ([salt] / [acid]), the salt is Na2HPO4 and the acid is NaHzPO4.

How do you calculate phosphate replacement?

Supplementation dose was calculated according to the equation: phosphate dose (in mmol) = 0.5 x body weight x (1.25 – [serum phosphate]). Sodium-potassium-phosphate was infused at a rate of 10 mmol/hour.
