i was trying to work out the problem (1.00x)50/15x.
(x=.40g this is the answer)
when i work it out i get 5050x/15x but i dnt understand how this equals .40?? help plse

There has to be an equal sign in the initial equation if you are going to find x. So what is the real equation?

ok so the real eq is 5.0=k=c1/c2=
1.00gx/15mlall over x/50 ml =
(1.00x)50/15x
the answer comes out ot .40g
