10.6 mol
To find the number of moles, you first need to determine the molar mass of calcium fluoride, which is 78.07 g/mol. Then, divide the given mass by the molar mass: 12.8 g / 78.07 g/mol = 0.164 moles. Therefore, there are 0.164 moles in 12.8 g of calcium fluoride.
.913 moles
To find the number of moles in 80 grams of calcium, you would first calculate the molar mass of calcium (40.08 g/mol), then divide the given mass by the molar mass to get the number of moles. In this case, 80 grams of calcium would be 2 moles.
The molar ratio between calcium carbonate and calcium oxide is 1:1. So, 25 moles of calcium carbonate will produce 25 moles of calcium oxide. The molar mass of calcium oxide is 56.08 g/mol, so the mass of calcium oxide produced will be 25 moles * 56.08 g/mol = 1402 g.
To find the number of moles in 28 grams of calcium oxide, we need to divide the given mass by the molar mass of calcium oxide. The molar mass of calcium oxide (CaO) is 56.08 g/mol. So, 28 grams of CaO is equal to 28 g / 56.08 g/mol = 0.5 moles of calcium oxide.
425 g calcium (Ca) is equal to 10,604 moles.
The answer is 1.35 moles.425 g of UF4 would be 1.35 moles.
29,0 g of calcium is equal to 0,723 moles.
0,06 g calcium is equivalent to 0,0015 moles.
0,27 moles of calcium contain 10,82 g calcium.
3 moles of calcium is equivalent to 120,234 g.
There are approximately 1 mole of calcium in 40 g, as the molar mass of calcium is about 40 g/mol.
978 g calcium contain 24,4 moles.
120 g calcium is equal to 3 moles.
400 g of calcium cabonate is equal to 3,996 moles.
156 g calcium is equivalent to 3,89 moles.
0,688 g calcium is equivalent to 0,017 moles.
