0.625 moles Ca3N2 (3 mole Ca/1 mole Ca3N2)(6.022 X 10^23/1 mole Ca) = 1.13 X 10^24 calcium ions
0,27 moles of calcium contain 10,82 g calcium.
120 grams of calcium contain 2,994 moles.
29,0 g of calcium is equal to 0,723 moles.
425 g calcium (Ca) is equal to 10,604 moles.
0.4469mol in 75g
The chemical formula for calcium chloride is CaCl2, and its formula weight is 110.99. The formula shows that each formula weight of calcium chloride contains one mole of calcium ions. In 166.5 grams, there are 166.5/110.99 or 1.500 formula weights of calcium chloride and the same number of moles of calcium ions.
CaTiO3 has one Ca2+ ion, so 1x0.25=0.25mol
The formula unit for calcium chloride is CaCl2. There are two chloride ions in one formula unit of calcium chloride. We can also say that there are two moles chloride ions in one mole of CaCl2.
I suppose that the answers are: - 0,9 moles aluminium ions - 2,7 moles chloride ions
0.00833 moles of CO3
0.625 moles Ca3N2 (3 mole Ca/1 mole Ca3N2)(6.022 X 10^23/1 mole Ca) = 1.13 X 10^24 calcium ions
There are 2.8604 moles of ammonium ions in 6.955.
42,5 grams calcium is equivalent to 1,06 moles.
3(2.6) = 7.8 moles of ions
0,27 moles of calcium contain 10,82 g calcium.
3 moles of calcium is equivalent to 120,234 g.
