Answer:
- 637.636 mL of NaF
- 0.7014 moles of SrF2
Explanation:
= 
Where 1 and 2 represent NaF and SrCl2 respectively; and C and V ae concentration and volume.
0.110 × V1 = 0.420 × 167
<em>V1 = </em>
<em> = 637.636 mL ≈ 0.638 L.</em>
Mole ratio of SrF2:
mole ratio of SrCl2 : SrF2 is 1 : 1 (also, conc × vol = no. of moles )
<em>∴ moles of SrF2 = 0.7014.</em>
