How many moles of a nitrate ion are in 2.50 moles calcium nitrate?
Calcium Nitrtae is Ca(NO3)2 and so there are two moles of nitrate per mole of calcium nitrate. Thus there are 2 x 2.50 = 5.0 moles of nitrate present.
How many moles of nitrate ion are present in 5.600grams of calcium nitrate?
To find the number of moles of nitrate ion in calcium nitrate, first calculate the molar mass of calcium nitrate (Ca(NO3)2). This is 164.09 g/mol. Divide the given mass (5.600 g) by the molar mass to get the number of moles, which is 0.034 moles. Since there are two nitrate ions in one calcium nitrate molecule, multiply the number of moles by 2 to get the number of moles of nitrate ions, which is 0.068 moles.
How many moles of ions are produced by the dissociation of 0.5 mol of Na2CO3?
When Na2CO3 dissociates, it produces 3 moles of ions: 2 moles of Na+ ions and 1 mole of CO3^2- ions. So, if you have 0.5 moles of Na2CO3, you would produce 1.5 moles of ions in total.
How many moles of calcium atoms are 2.5 moles of calcium carbonate CaCO3?
The formula given shows that each formula unit or mole contains one calcium atom; therefore, 2.5 moles of calcium chloride contains 2.5 moles of calcium atoms.
How many moles of calcium oxide are produced when 36.5 g of calcium react completely with oxygen gas?
.913 moles
How many moles of Ca2 ions are in 75 of calcium titanate?
0.4469mol in 75g
How many ions or atoms of calcium and chloride in 1.5 moles of CaCl2?
In 1.5 moles of CaCl2, you would have 3 moles of ions or atoms of calcium and 3 moles of ions of chloride. Since CaCl2 dissociates into 1 calcium ion (Ca2+) and 2 chloride ions (2Cl-), this means you would have 3 moles of calcium ions and 6 moles of chloride ions in total.
How many moles of a nitrate ion are in 2.50 moles calcium nitrate?
Calcium Nitrtae is Ca(NO3)2 and so there are two moles of nitrate per mole of calcium nitrate. Thus there are 2 x 2.50 = 5.0 moles of nitrate present.
How many moles of Ca are there in 0.18moles of Ca F2?
There are 0.18 moles of Ca2+ ions in 0.18 moles of CaF2.
How many chloride ions are in calcium chloride?
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.
How many moles of calcium ions are present in 166.5grams of calcium chloride?
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.
How many moles of ions AL3 and how many mols of ions CL-has in 0.9 mols of ALCL3?
I suppose that the answers are: - 0,9 moles aluminium ions - 2,7 moles chloride ions
How many calcium ions in an 8.0 mole sample of calcium phosphate?
The formula unit for the most common form of calcium phosphate is Ca3(PO4)2. Therefore each formula unit, the ionically bonded counterpart of a mole for covalently bonded compounds, contains three calcium ions. The number of calcium ions in 8.0 "moles" of calcium phosphate is 3 [exact] X 8.0 X Avogadro's Number or 1.45 X 1025 atoms, where the depressed last digit of 1.45 indicates that this digit may not be significant. (The significant-digits-limiting datum is 8.0 moles.)
How many moles of calcium are in 42.5 grams calcium?
42,5 grams calcium is equivalent to 1,06 moles.
How many moles of nitrate ion are present in 5.600grams of calcium nitrate?
To find the number of moles of nitrate ion in calcium nitrate, first calculate the molar mass of calcium nitrate (Ca(NO3)2). This is 164.09 g/mol. Divide the given mass (5.600 g) by the molar mass to get the number of moles, which is 0.034 moles. Since there are two nitrate ions in one calcium nitrate molecule, multiply the number of moles by 2 to get the number of moles of nitrate ions, which is 0.068 moles.
How many grams is contained in 0.27 moles of calcium?
0,27 moles of calcium contain 10,82 g calcium.
How many calcium ions in 0.625 mol of calcium nitride?
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
