Help!!!!!!!!!!!!!!!!!!!!!!!!!!?

Question

I have to solve the following problems and I am just lost I need to find the theoretical molarity of the base useing this formula
M acid x V acid = M base x V base
Volume of acid (mL) actually used 25.00


Molarity of acid actually used (mol/L) 0.24


Volume of base (mL) actually used 8.03, 7.72, 7.62 (I need to solve the problem three time useing each one of these)

Theoretical Molarity of base, based upon formula from above(show your work):

Thanks for you help, I think my rain has stoped working.

Answer 1

(MV)acid=(MV)base

(25mlX0.24mol/L)/(8.03L)=.747mol

Now you do the rest. Its not hard. Its like solving for X.

Answer 2

First take the formula
Ma Va = Mb Vb

You need to know the Molarity of the base. So rearrange for this
Mb = Ma * Va / Vb
As both Va and Vb are in ml there is no need to convert to L. So you just need to plug in the figures to get the result.

Eg The first
Mb = 0.24 * 25 / 8.03
= 0.74 M

Just repeat for the rest

Answer 3

I'm not sure what your issue is here.

You have the correct equation and 3 of the 4 pieces. Just plug in and solve
