(x=.40g this is the answer)
when i work it out i get 50-50x/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=
1.00g-x/15mlall over x/50 ml =
the answer comes out ot .40g
