Question

please help
I collected this data at the end of a titration lab. what is the concentration of the acid ? show work.
this was the data I collected
0.20 molar NaOH
30 ml NaOH
45 mL HCI

Answer 1

You can find it out like this:

NaOH + HCl => NaCl + H2O
0.20 M 30 ml NaCl has 0.20x30x10^-3 moles=0.06 moles....

That means 0.06 moles of HCl were also involved......

So.... \[M=\frac{ No. of moles }{ Volume [ ltr ]}\]

Answer 2

Which would come up to be....0.166 M

Answer 3

omg thank you so much

Answer 4

Anytime.....:D
