What volume in mL of 0.300 M NaF would be required to make a 0.0715 M solution of NaF when diluted to 250.0 mL with water

The volume of 0.300 M NaF required is 59.6 ml

Explanation:

According to the dilution law,

where,

= concentration of concentrated NaF solution = 0.300 M

= volume of pure concentrated Na F solution = ?

= concentration of diluted NaF solution= 0.0715 M

= volume of diluted NaF solution= 250.0 ml

Thus the volume of 0.300 M NaF required is 59.6 ml

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
