0,27 moles of calcium contain 10,82 g calcium.
5,26 moles of oxygen contain 31,676.10e23 atoms.
Two moles of neon contain 12,044281714.10e23 atoms.
382 g Co contain 6,482 moles.
The number of moles of calcium carbonate are 3.5 moles. , there are 1 mole of calcium (Ca) atom, 1 mole of carbon (C) atom and 3 moles of oxygen (O) atoms.
0,27 moles of calcium contain 10,82 g calcium.
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.
5,26 moles of oxygen contain 31,676.10e23 atoms.
Two moles of neon contain 12,044281714.10e23 atoms.
0,4 moles calcium have 2,408 856 342 8.1023 atoms.
0,688 g calcium is equivalent to 0,017 moles.
There are 0.18 moles of Ca2+ ions in 0.18 moles of CaF2.
To find the number of moles, we need to divide the given mass of cobalt (382g) by its molar mass, which is approximately 58.93 g/mol. Therefore, 382g of cobalt contains approximately 6.48 moles of atoms.
To find the number of atoms in 159g of calcium, you need to first calculate the number of moles of calcium present using the molar mass of calcium. The molar mass of calcium is approximately 40 g/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of calcium to atoms. Calculate the number of moles of calcium in 159g using the formula: moles = mass (g) / molar mass (g/mol). Finally, multiply the number of moles by Avogadro's number to determine the number of atoms in 159g of calcium.
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.
The formula unit for calcium is a single atom. Therefore, the number of moles may be found by dividing the given number of atoms by Avogadro's number, or 1.999 moles.
382 g Co contain 6,482 moles.
