Question

What volume of a 9.00 M NaOH stock solution would you need to make 800. ML of a 0.750 M NaOH solution

Answer 1

Answer: 66.66 ml

Explanation: Using Molarity equation:

`M_1V_1` (stock solution)=
`M_2V_2`(solution to be prepared)

given:
`M_2=0.750M`

`V_2=800ml`

`M_1=9.00M`

`V_1=?`

`9.00M* V_1` (stock solution)=
`0.750M* 800ml` (solution)

`V_1= 66.66ml`
