the mass of Ca3(PO4)2 is 310.18g This is because Calcium's mass is 40.08g and you have to times it by 3. Then you add phosphorus which is 30.97g times 2. Lastly, add oxygen's mass which is 16.00g times 8 because 4*2 is 8. (40.08g*3)+(30.97g*2)+((16.00g*4)*2)=310.18g
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.
The molar mass of copper phosphate (Cu3(PO4)2) is approximately 380.58 g/mol.
The molar mass of calcium acetate is approximately 142 g/mol.
To find the mass percent of hydrogen in ammonium phosphate NH4 3PO4, first calculate the total molar mass of the compound. Then, determine the molar mass contributed by hydrogen. Finally, divide the molar mass of hydrogen by the total molar mass of the compound and multiply by 100 to get the mass percent.
Ammonium phosphate ((NH4)3PO4) contains one phosphorus atom in the formula. To calculate the percent composition by mass of phosphorus, you need to find the molar mass of phosphorus and the molar mass of the entire compound. Then, divide the molar mass of phosphorus by the molar mass of the compound and multiply by 100 to get the percentage.

To find the mass of calcium phosphate (Ca₃(PO₄)₂) in grams for 0.658 moles, first calculate its molar mass. The molar mass of calcium phosphate is approximately 310.18 g/mol. Multiply the number of moles by the molar mass: 0.658 moles × 310.18 g/mol ≈ 204.4 grams. Thus, there are about 204.4 grams of calcium phosphate in 0.658 moles.
To calculate the number of moles in 150g of calcium phosphate, you need to first determine the molar mass of calcium phosphate (Ca3(PO4)2), which is 310.18 g/mol. Then, divide the given mass of calcium phosphate by its molar mass to get the number of moles. In this case, 150g / 310.18 g/mol ≈ 0.48 moles.
To find the mass in grams of 2.3 x 10^-4 moles of calcium phosphate (Ca3(PO4)2), you first need its molar mass. The molar mass of calcium phosphate is approximately 310.18 g/mol. Therefore, the mass can be calculated as follows: 2.3 x 10^-4 moles × 310.18 g/mol ≈ 0.0713 grams.
Balanced equation first. Ca3(PO4)2 + 3H2SO4 -> 3CaSO4 +2H3PO4 1.523 moles H2SO4 (1 mole Ca3(PO4)2/3 moles H2SO4)(310.18 grams/1 mole Ca3(PO4)2) = 157.5 grams of Calcium phosphate

The molar mass of CaSO4 is approximately 136.14 g/mol. The molar mass of calcium in CaSO4 is 40.08 g/mol. To find the percent composition of calcium in CaSO4, divide the molar mass of calcium by the molar mass of CaSO4 and multiply by 100. The percent by mass of calcium in CaSO4 is approximately 29.45%.
Well, honey, the molar mass of strontium phosphate is approximately 182.24 grams per mole. It's like the weight of all the strontium and phosphate atoms in one mole of the compound, simple as that. So, if you need to calculate some stoichiometry or impress your chemistry teacher, now you know!
The molar mass of lead(III) phosphate (Pb3(PO4)2) can be calculated by adding the molar mass of lead (Pb) and the molar mass of phosphate (PO4) in the compound. The molar mass of Pb is 207.2 g/mol and the molar mass of PO4 is 94.97 g/mol. Therefore, the molar mass of Pb3(PO4)2 is 3(207.2) + 2(94.97) = 611.54 g/mol.
To find the number of moles in 3.75 grams of calcium, divide the mass of calcium by its molar mass. The molar mass of calcium is approximately 40.08 g/mol. Therefore, 3.75 grams of calcium is equal to 0.0936 moles.
