To find the number of atoms, first convert the mass of calcium (179 g) to moles using the molar mass of calcium (40.08 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of calcium to atoms. Calculate as follows: 179 g / 40.08 g/mol = 4.47 mol x 6.022 x 10^23 atoms/mol = approximately 2.69 x 10^24 atoms.

How many atoms are in 147 g of calcium?
Quite a few! 147 grams calcium (1 mole Ca/40.08 grams)(6.022 X 1023/1 mole Ca) = 2.21 X 1024 atoms of calcium ----------------------------------------
How many atoms are in 0.0010 grams of calcium?
To calculate the number of atoms in 0.0010 grams of calcium, you would first convert the mass to moles using the molar mass of calcium. Then, you would use Avogadro's number to convert moles to atoms. The formula would be: (0.0010 g / 40.08 g/mol) * 6.022 x 10^23 atoms/mol.
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.
