How can calculate equivalent weight of calcium carbonate?
The equivalent weight of calcium carbonate can be calculated by dividing its molecular weight by the number of acidic hydrogen ions that it can donate in a reaction. In the case of calcium carbonate, it can donate two moles of hydrogen ions, so the equivalent weight would be its molecular weight divided by 2.
What percentage of calcium gluconate is calcium?
Calcium gluconate contains approximately 9% elemental calcium by weight.
What is the atomic weight for calcium?
40.078
What is the mass of calcium?
The atomic weight of calcium is 40,078 +/- 0,004 (IUPAC, 2005).
What is the formula weight of calcium fluoride?
To calculate the formula weight of calcium fluoride (CaF2), you would add the atomic weights of calcium (Ca) and two atoms of fluorine (F). The atomic weight of calcium is 40.08 g/mol and the atomic weight of fluorine is 18.998 g/mol. Therefore, the formula weight of calcium fluoride is 40.08 + 2(18.998) = 78.076 g/mol.
Does more calcium make lose weight?

How the equivalent weight of calcium phosphate be calculated?
The equivalent weight of calcium phosphate is calculated by dividing the molar mass of calcium phosphate by the valency factor of the phosphate ion. Since calcium phosphate is a salt with the formula Ca₃(PO₄)₂, its molar mass is calculated by adding the molar masses of calcium and phosphorus (since there are three calcium ions and two phosphate ions in the formula). The valency factor of phosphate ion is 2 since it can donate or accept 2 electrons.
What is the element that has atomic weight 40?
Calcium has an atomic weight of 40. Other info about Calcium: Symbol: Ca Name: Calcium Atomic Number: 20 Atomic Weight: 40.08 Number of Neutrons: 20 (atomic weight - atomic number) Number of Protons: 20
What is the percent of water in calcium sulfate?
Calcium sulfate, also known as gypsum, typically contains about 20% water by weight.
What is molecular weight of calcium?
40 or 40.08 to be very precise.
What is the equivalent weight of calcium chloride?
The equivalent weight of calcium chloride (CaCl2) is 55.5 g/mol. This is the amount of the compound that can donate or accept one mole of electrons in a reaction.
What is the atomic mass of calcium?
The atomic weight of calcium is 40,078 +/- 0,004 (IUPAC, 2005).
