The molar mass is 310.174 g/mol.
What is the percentage of calcium in calcium carbonate?
To calculate the mass percent of calcium, substitute the value of atomic mass of calcium and atomic mass of calcium carbonate in the given formula. Therefore, the percentage of calcium in calcium carbonate is 40.04%.
What is the percentage of phosphorus in magnesium phosphate?
Answer: the percentage of phosphorus in magnesium phosphate is 23.567% .
What is the equivalent weight of MnSO4?
The equivalent weight of MnSO_(4) is half its molecular weight when it is converted to. If valency is 2, then equivalent weight will be equal to its molecular weight. Thus, when MnSO4 is converted into MnO2, then the valency factor is 2, and the equivalent weight of MnSO4 will be half of its molecular weight.

What is the mass of a boron trichloride molecule?
NamesChemical formulaBCl3Molar mass117.17 g/molAppearanceColorless gas, fumes in airDensity1.326 g/cm3
How do you calculate phosphorus from 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.
