Ah, the molecular weight of 7H2O, or water, is about 126.14 grams per mole. Isn't that just a lovely number? Remember, understanding the molecular weight helps us appreciate the beauty and harmony of chemistry.
Sodium dihydrogen phosphate heptahydrate is a chemical compound with the formula NaH2PO4·7H2O. It is a white, crystalline solid that is soluble in water. This compound is commonly used as a buffering agent in biochemical and molecular biology applications.
It has a molecular weight of 21,600 Daltons
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
Potassium permanganate has a higher molecular weight compared to methylene blue. The molecular weight of potassium permanganate is approximately 158.03 g/mol while the molecular weight of methylene blue is around 319.85 g/mol.
The formula for silver nitrate is AgNO3. Its molecular weight is 169.87g/mol.
1. Find the molar mass (MM) of the substances.MM FeSO4 = 151.91g+MM 7H2O = 126.11gMM FeSO4 x 7H2O = 278.02g2. Find the percent water of hydrate.Divide the mass of water by the mass of the hydrate; multiply result by 100%.126.11g278.02g x 100%Percent water of FeSO4 * 7H2O is 45.36%.Finding Molar Mass# atoms Element A x atomic mass Element A = Mass A# atoms Element B x atomic mass Element B = Mass B... etc.Add up all the mass values for the substance and you have the molar mass of the substance.
molecular weight of NiSO4.7H2O is 1101.3 and it has 11 oxygens. So percentage of oxygen = (7 x 16) / 1101.3 = 112 / 1101.3 = 0.102 or 10.2%
