Sep 8, 2023Instant Answer EXPERT VERIFIED Step 1/3 Step 1: Determine the molar mass of calcium. The molar mass of calcium (Ca) is 40.08 g/mol. Step 2/3 Step 2: Calculate the number of moles of calcium in 143 g. Number of moles = mass / molar mass Number of moles = 143 g / 40.08 g/mol Number of moles = 3.567 mol Answer
Answered: How many moles of calcium atoms do you… | bartleby
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

Suppose you have 10 gram of carbon. Now, it should be converted in terms of atoms. We know that the molar mass of 1 mole of carbon is equal to 12. It means that 12 grams per mole. Also, the Avogadro constant is 6.02 x 10 23. So, the conversion of carbon from grams to atoms is given by = 10(1/12)( 6.02 x 10 23) = 5.02 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
