Question

1

Answer 1

Ok, so how many Hg2+ are there in 1mol of Hg2(NO3)2

Answer 2

there are 2 Hg

Answer 3

And how about NO3? still 2 right?

Answer 4

And it is simple math from now

Answer 5

you are correct

Answer 6

what do you mean? simple math

Answer 7

if you have N mol of a molecular in 1mole of solution solution, how many moles are there in .5M, how about .05M?

Answer 8

would it be, if they have a 2:2 relationship.... they would both be the same at 0.05M ?

Answer 9

of cuz

Answer 10

oh! so 3 of 5 are gone now!

Answer 11

I guess the answer is the 1st one, but i don't get why

Answer 12

well, I am going to say it explicitly now. 0.05*2=0.1, get it?

Answer 13

so because each has 2 moles.... you multiply the moles by the 0.05 M, each one is .1 that means the answer is the 3rd choice

Answer 14

Exactly
