Question

if you add 50 mL of water to 100mL of a 0.15M NaOH solution what will be the molarity of the diluted solution

Answer 1

0.1M

Step-by-step explanation:

Molarity =
`(mole)/(volume)`

Let d be the diluted solution, let i be the initial solution

`C_(d) V_(d) = C_(i)V_(i)`

`C_(d) = (C_(i)V_(i))/(V_(d))`

= 0.15 x (100x10^-3) / (50x10^-3)+(100x10^-3)

= 0.1 M
