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

About this tutor ›. Avogadro’s number = 6.02×10 23 particles per mol (particles can be atoms, molecules, formula units, etc) atomic mass Ca = 40.08 g / mol. moles Ca = 3456 g x 1 mol / 40.08 g = 86.228 moles. atoms of Ca = 82.228 moles x 6.02×10 23 atoms / mol = 519.1×10 23 atoms = 5.191×10 25 atoms of Ca.

How Many Atoms Are In 123 G Of Calcium
Sep 8, 2023Step 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 Step 3: Calculate the number of atoms in 3.567 moles of calcium. Avogadro’s number states that there are 6.022 x 10^23 atoms in one mole of any substance. Therefore, 143 grams of calcium contain: N = 143 g × 6.022 × 1 0 23 m o l − 1 40.08 g m o l = 2.15 × 1 0 24 \beginaligned N&=\frac\pu143 g \times 6.022 \times 10^23 mol^-1\pu40.08 \fracgmol\\ &=\pu2.15 \times 10^24 \endaligned N = 40.08 mol g 143 g × 6.022 × 1 0 23 mo l − 1 = 2.15 × 1 0 24 2.15 × \times × 10 24
