Ca+2 PO4-3 <---- these are the ions and their charges
Ca+2 Ca+2 Ca+2 PO4-3 PO4-3 <---- the charges have to add up to zero, so three +2 calcium ions cancel out two -3 phosphate ions
Ca3(PO4)2 <---- simplify

∙ 12y agoThese are the ions and their charges: Ca+2 PO4-3
The charges have to add up to zero, so three +2 Ca ions and two -3 P ions are added in order to cancel each other out: Ca+2 Ca+2 Ca+2 PO4-3 PO4-3
Simplify: Ca3(PO4)2

A mass of 21.5 grams of calcium hydroxide reacts with an excess of phosphoric acid What mass of calcium phosphate could be recovered from solution?
31.6grams
Calculate number of grams of sodium in 7.2 grams of sodium phosphate?
The gram atomic mass of sodium is 22.9898, the formula of the least hydrated form of sodium phosphate is Na3PO4.10 H2O, and the gram formula unit mass of this sodium phosphate is 344.09. Therefore, the mass fraction of sodium in this sodium phosphate is 3(22.9898)/344.09 or about 0.20044, and the grams of sodium in 7.2 grams of this sodium phosphate is 1.44 grams of sodium, to the justified number of significant digits.
How many milligrams of calcium are present in 500 mg tablet of calcium carbonate?
The formula for calcium carbonate is CaCO3, and it has a gram formula mass of 100.09. The formula shows that each formula mass contains one calcium atom, which has a gram atomic mass of 40.08. Therefore, the mass fraction of calcium in calcium carbonate is 40.08/100.09, so that a 500 mg tablet of calcium carbonate contains 200 mg of calcium, to the justified number of significant digits.
What is the concentration of a solution that has a volume of 2.5 L and contains 660 g of calcium phosphate?
Find the atomic mass of calcium phosphate [ Ca3(PO4)2 ]Ca3 = 120.3P2 = 62O8 = 128Total Atomic Mass = 310.3Moles= mass/atomic massMoles = 660/310.3Moles = 2.127M (Concentration) = moles/litresM= 2.127 mol/2.5LM= 0.8508Concentration = 0.8508M
What is the formula mass of calcium acetate?
Calcium acetate, or Calcium ethanoate, has the molecular formula (CH3COO)2Ca. The atomic weights of Carbon, Hydrogen, Oxygen and Calcium are 12, 1, 16 and 40, respectively. So, the formula mass is 2 x ((1 x 12) + (3 x 1) + (2 x 16)) + (1 x 40) = 134
What is the formula mass of calcium phosphate?
310.18 amu
What accounts for almost two-thirds of the mass of bone tissue?
Calcium phosphate (This answer was found in my Anatomy book)
How many grams of phosphorus are in 500 grams of calcium phosphate?
The mass of phosphorus of any sample of calcium phosphate is the mass of the same multiplied by the percentage that phosphorus makes up of that sample. (mass of sample) x (mass of phosphorus/total mass) Therefore we must look at the chemical formula of the substance in question: Ca3(PO4)2. From this we can see that there are 2 phosphorus atoms attributing mass to the total molecule. The formula becomes: 500 g x 2x30.97 g/mol/310.17 g/mol = 99.8 g molar mass of phosphorus: 30.97 g/mol molar mass of calcium phosphate: 310.17 g/mol total mass: 500 g

How many moles of calcium phosphide are in 444g?
The chemical formula for calcium phosphide is Ca3P2.Formula mass of Ca3P2 = 3(40.1)+2(31.0) = 182.3Amount of Ca3P2 = mass of sample / formula mass = 444/182.3 = 2.44mol
Calculate number of grams of sodium in 7.2 grams of sodium phosphate?
The gram atomic mass of sodium is 22.9898, the formula of the least hydrated form of sodium phosphate is Na3PO4.10 H2O, and the gram formula unit mass of this sodium phosphate is 344.09. Therefore, the mass fraction of sodium in this sodium phosphate is 3(22.9898)/344.09 or about 0.20044, and the grams of sodium in 7.2 grams of this sodium phosphate is 1.44 grams of sodium, to the justified number of significant digits.
How many grams calcium are in 100 grams calcium chloride?
The formula of anhydrous calcium chloride is CaCl2, and its gram formula mass is 110.99. The gram atomic mass of calcium is 40.08. Therefore, the grams of calcium in 100 grams of calcium chloride is 100(40.08/110.99) or 36.11 grams, to the justified number of significant digits.
