Elementary Charge- NEED HELP!!!

Object 1, a conductor with a positive charge og 0.02 C is brought into contact with an identical neutral object 2.

How many electrons move from one object to the other and in which direction?

My Work..

I know that we need to use the formula Q=ne and we have the value for Q (0.02C). We can also use teh constant for e which is 1.60 * 10 6 -19 ... i do not know the signs of teh two values... Please tell me if i am on the right path.. and help me solve the problem.. Thank you.

Forget the formulas. You know the charge will distribute itself equally on both objects, since they are identical.

???

So.. the charge will be 0.01C on both and electrons will be transferred from #1 to #2....????
