How many atoms are in 1.25 moles of calcium acetate, ca(c² h³ o²)²?

7.52767607125× 10^23 atoms

Explanation:

The Avogadro number/constant indicates that  they are 6.022140857 × 10^23 number of units (atoms) in one mole of any substance. Therefore, in this case, ti find the number of atoms in 1.25 moles of calcium acetate, well multiply the two number;

6.022140857 × 10^23 * 1.25 = 7.52767607125× 10^23

43.452

step-by-step explanation:

284 times .153 = 43.452
