Question

How many moles of chlorine are there in 16.0 mL of 0.450 M CaCl2?

0.0072 mol
0.0144 mol
0.0216 mol
0.0375 mol
none of the above

I had chose 0.0072 and had submitted it in my assignment, but it had said it was wrong. I chose 0.0072 because I did this equation: 16/ 1000*0.450 and got 0.0072.

Answer 1

I got to agree that it is 0.0072

Answer 2

but that is wrong when entered into assignment, what else could it be

Answer 3

then you must times it by two so it would be .0144
