The molar mass of copper(ii) chloride (cucl2) is 134.45 g/mol. how many formula units of cucl2 are present in 17.6 g of cucl2?

Im not sure if formula units are equivalent to moles but I am gonna solve this as if they are lol. So 17.6 g is the given. You want to divide by your molar mass to cancel out the grams. Then you are left with moles as the unit for your final answer.

(17.6 g CuCl2 x 1 mol CuCl2)/(134.45 g/mol CuCl2)

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other

c. electrical charges of ionic bonds.

i hoped this , can i get brainliest plzgod bless you
