Ca: 40.1
O: 16.0×2 = 32.0
H2: 1.0×2 = 2.0
Ca(OH)2: 74.1 grams
(40.1 ÷ 74.4) × 100 = 53.9 % of Ca in Ca(OH)2
53.9 % of 5.00 grams = 2.67 grams of Ca in Ca(OH)2

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 calcium ca atoms are in 98.5 g of ca?
To determine the number of moles of calcium atoms in 98.5 g of Ca, you need to first calculate the molar mass of Ca (40.08 g/mol). Then, divide the given mass by the molar mass to get the number of moles. So, 98.5 g of Ca is equal to 98.5 g / 40.08 g/mol ≈ 2.46 moles of Ca atoms.
How many moles are in forty grams of calcium?
For this you need the atomic mass of Ca. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.40.0 grams Ca / (40.08 grams) = .998 moles Ca
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 atoms are in 500.00 mg of calcium?
Calcium hydroxide (Ca(OH)2) has a molar mass of 74g/mol. To find the number of moles in 0.5000g of calcium hydroxide, you divide the 0.5000gCa(OH)2 by 74gCa(OH)2. The answer is 0.006757mol Ca(OH)2 to the nearest significant figure.
How many moles of calcium are in 425 g calcium (Ca)?
425 g calcium (Ca) is equal to 10,604 moles.
How many moles of ca would be in 3.8G?
3.8 grams calcium (1 mole Ca/40.08 grams) = 0.09 moles calcium ==============
How many moles of calcium is 126g of ca?
126 grams calcium (1 mole Ca/40.08 grams) = 3.14 moles of calcium ------------------------------
How many moles are in 16.5g 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.
How many moles are in 978 g Ca?

How many moles of carbon are in 3.5 moles of calcium carbonate?
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.
How many moles of calcium atoms are in 45.8 g of Ca?
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.
How many moles of atom contained in 0.688 g Ca?
0,688 g calcium is equivalent to 0,017 moles.
How many grams is contained in .27 moles of calcium?
(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.
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.
