Question

Calculate the moles of Cl atoms in 0.0814 g of C2H4Cl2.

Answer 1

Answer:

2(C) + 4(H) + 2(Cl). Divide the given mass of C2H4Cl2 by the molecular weight. That gives the number of moles of C2H4Cl2. Finally, multiply the number of moles of C2H4Cl2 by 2 to get the number of moles of Cl atoms.
