Avogadro’s number is thus the link between the macro world of grams and kilograms, that which we can directly measure, and the micro world of atoms and molecules, about which we can conceive. So moles of Ca = 183.08 ⋅ g 40.078 ⋅ g ⋅ mol−1 = approx. 4.5 ⋅ mol. Number of calcium atoms = 4.5 ⋅ mol ×6.02247 ×1023 ⋅ mol−1 = ??how many calcium atoms

You find the molar mass of calcium metal, it is listed as 40.1⋅ g ⋅ mol−1. You should check your copy of the Periodic Table to see if I have got it right. This means that Avogadro’s number of calcium atoms, i.e. 6.022 × 1023 individual calcium atoms have a mass of 40.1 ⋅ g.

Step 2/3. 2. Calculate the number of moles of calcium in 179 g: n = m/M = 179 g / 40.08 g/mol = 4.46 mol. Answer. 3. Calculate the number of atoms in 4.46 mol of calcium: One mole of any element contains Avogadro’s number of atoms, which is 6.022 x 10^23.

1 Answer Nathan L. Jun 7, 2017 2.30 ×1024 atoms Ca Explanation: We’re asked to calculate the number of atoms of Ca in 153 g Ca. What we must first do is convert the given mass of calcium to moles of calcium, using its molar mass (referring to a periodic table, this is 40.08 g mol ): 153 g Ca( 1mol Ca 40.08g Ca) = 3.82 mol Ca
