Question

CALCULATE MOLE OF CHLORINE ATOM IN 0.822 GRAM OF C2H4Cl2

Answer 1

Answer:

divide grams by the molar mass of C2H4Cl2 to get moles of C2H4Cl2 and then multiple that number by 2 because there is a 2:1 ratio of Cl atoms to C2H4Cl2 molecules

1.66 * 10 ^ -2 moles of chlorine

hope it helps u and follow me

Answer 2

Explanation:

formula is No of atom in O is = Molar mass × given no of molecules ÷ 6.02×10²³

========== 64×2.6×10²⁰÷6.02×10²³

========== 166.4×10²⁰÷6.02×10²³

========== 2.7×10-⁴ Answer
