425 g calcium (Ca) is equal to 10,604 moles.
To find the number of moles in 16.5g of calcium, first determine the molar mass of calcium (Ca), which is approximately 40.08g/mol. Then, divide the given mass by the molar mass to get the number of moles. In this case, 16.5g ÷ 40.08g/mol ≈ 0.411 moles of calcium.
978 g calcium contain 24,4 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.
(2.7 mol Ca / 1) * (40.078 g Ca / 1 mol Ca) = 108.21 g Ca. After significant figures, the answer is 110 g Ca.
Calcium bicarbonate has the chemical formula Ca(HCO₃)₂. In two moles of calcium bicarbonate, there are 2 moles of calcium (Ca), 4 moles of hydrogen (H), and 4 moles of oxygen (O). Therefore, the total number of atoms is 2 (Ca) + 4 (H) + 4 (O) = 10 atoms per two moles of calcium bicarbonate.
3.8 grams calcium (1 mole Ca/40.08 grams) = 0.09 moles calcium ==============
126 grams calcium (1 mole Ca/40.08 grams) = 3.14 moles of calcium ------------------------------
To find the number of moles in 16.5g of calcium, first determine the molar mass of calcium (Ca), which is approximately 40.08g/mol. Then, divide the given mass by the molar mass to get the number of moles. In this case, 16.5g ÷ 40.08g/mol ≈ 0.411 moles of calcium.
978 g calcium contain 24,4 moles.
There are 0.18 moles of Ca2+ ions in 0.18 moles of CaF2.
156 g calcium is equivalent to 3,89 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.
To determine the number of moles of calcium atoms in 45.8 g of Ca, first find the molar mass of calcium (Ca) from the periodic table (40.08 g/mol). Then, divide the given mass by the molar mass of Ca to get the number of moles. In this case, 45.8 g of Ca is equal to 1.14 moles of Ca atoms.
(2.7 mol Ca / 1) * (40.078 g Ca / 1 mol Ca) = 108.21 g Ca. After significant figures, the answer is 110 g Ca.
Calcium bicarbonate has the chemical formula Ca(HCO₃)₂. In two moles of calcium bicarbonate, there are 2 moles of calcium (Ca), 4 moles of hydrogen (H), and 4 moles of oxygen (O). Therefore, the total number of atoms is 2 (Ca) + 4 (H) + 4 (O) = 10 atoms per two moles of calcium bicarbonate.
0,688 g calcium is equivalent to 0,017 moles.
To find the number of moles, you need to divide the given mass of calcium by its molar mass. The molar mass of calcium (Ca) is approximately 40.08 g/mol. Number of moles = 77.4 g / 40.08 g/mol ≈ 1.93 moles.
