The formula mass of CaF2 is 40.1 + 2(19.0) = 78.1
Amount of CaF2 = 58.2/78.1 = 0.745mol
2,8 moles of calcium carbonate have 240,208 g.
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.
There are 0.18 moles of Ca2+ ions in 0.18 moles of CaF2.
126 grams calcium (1 mole Ca/40.08 grams) = 3.14 moles of calcium ------------------------------
To find the number of moles in 12.2 grams of calcium, divide the given mass by the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. Dividing 12.2 grams by 40.08 g/mol gives approximately 0.305 moles of calcium.
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.
Calculate the number of moles of calcium fluoride by dividing the mass by its molar mass. The molar mass of calcium fluoride (CaF2) is 78.08 g/mol. Then, multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the number of atoms present in 7.92g of calcium fluoride.
42,5 grams calcium is equivalent to 1,06 moles.
120 grams of calcium contain 2,994 moles.
7,68 grams of calcium nitride is equal to 0,052 moles.
There are 5 moles of calcium in 200 grams of calcium. This calculation is based on the molar mass of calcium, which is approximately 40 grams per mole.
3 moles of calcium is equivalent to 120,234 g.
4.5 moles
0,27 moles of calcium contain 10,82 g calcium.
To find the number of moles in 5000 grams of calcium, you need to divide the given mass by the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. So, 5000 grams of calcium is equal to 5000/40.08 = 124.69 moles of calcium.
3.8 grams calcium (1 mole Ca/40.08 grams) = 0.09 moles calcium ==============
120 g calcium is equal to 3 moles.
