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 much is 2 moles of sodium?

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.

How do you calculate molar mass quizlet?

Multiply the atomic weight of each element by the number of atoms of the element in the molecule, and add these to calculate the compound molar mass. In the example, the molar mass of Na2SO4 is (23 x 2) + (32 x 1) + (16 x 4) = 142 grams per mole.

What is molar mass simple?

Molar mass M is the mass of a chemical compound divided by its amount-of-substance measured in moles. It is defined as MB = m/nB, where m is the total mass of a sample of pure substance and nB is the amount of substance B given in moles.

What is meant by molar mass?

Molar mass is defined as the mass in grams of one mole of a substance. The units of molar mass are grams per mole, abbreviated as g/mol.

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 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 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.

How is number of moles calculated?

1 mole is a number equal to. 022 x 10 23 particles, also known as the Avogadro's constant. To calculate the number of moles of any substance in the sample, we simply divide the given weight of the substance by its molar mass.

How do you calculate the mass of product formed 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 the number of moles in each of the following masses?

To find the number of moles, we divide the given mass of the element by its atomic mass.

What is the sodium phosphate?

An inorganic compound used as a laxative, dietary supplement and for electrolyte-replacement purposes.

What is the use of sodium phosphate?

Sodium phosphate is used in adults 18 years of age or older to empty the colon (large intestine, bowel) before a colonoscopy (examination of the inside of the colon to check for colon cancer and other abnormalities) so that the doctor will have a clear view of the walls of the colon.

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.
