Question

Your teacher gives you 0.09 L of a 0.850 M solution of NaCl dissolved in water. What will the new volume be if you dilute it down to 0.500 M?

Answer 1

`V_2=0.153L`

Step-by-step explanation:

Hey there!

In this case, according to the equation for dilution process, in which the moles of the solute remain the same after the addition of additional solvent:

`M_1V_1=M_2V_2`

Thus, by solving for the new volume, V2, of the base, NaOH, we can obtain:

`V_2=(M_1V_1)/(M_2)=(0.09L*0.850M)/(0.500M)\\\\V_2=0.153L`
