Homework Help: chemistry desperately

Posted by diana on Tuesday, December 16, 2008 at 12:10am.

i am completely lost, i confused myself.

i need to find the concentration of HC2H3O2

HC2H3O2 + NaOH ==> NaC2H3O2 + HOH


NaOH
C= 0.3 M
v= 0.25 L
n= 0.075 moles
M= 40.00g/mol
m= 3.00 g

NaC2H3O2
n= 0.075 moles
m= 0.4973 g(ammount of acetic acid in
solution)

HC2H302
v= 0.020 L
M= 60.06g/mol


thats all the information i have. i dont know how to calculate it. my friend said c1v1=c2v2 but i dont know what numbers id use
