Question

I need help with finding the Concentration of HCL (Ma)

the other things I have right now are

Vb = 10ml

Va = 10ml

Mb = 0.25m

Answer 1

0.35 M

Step-by-step explanation:

HCl + NaOH --> NaCl + H2O

Since the ratio HCl : NaOH is 1:1, you can apply the formula:

Ma x Va = Mb x Vb

Vb = 14 ml (based on the table)

Va = 10 ml

Mb = 0.25 M

Ma = (Mb x Vb)/Ma = (14 x 0.25)/ 10 = 0.35 M
