This question provides us –
- Weight of  is = 47 g is = 47 g
- Volume, V = 375 mL

- Molar Mass of  – –
 
 
 
 
<u>Using formula</u> –
 
 
 
 
 
 
 
 
 
 
 
 
- Henceforth, Molarity of the solution is = 1.7M

                NaBr + CaF2 → NaF + CaBr2 What coefficients are needed to balance the chemical equation? A)	1,1,1,1 B)	1,2,1,2 C)	1,2,2,1 D)	2,1 
                elena-s [515]             
         
        
D.
2NaBr + CaF2 --> 2NaF + CaBr2 gives you:
2Na                        2Na
2Br                         2F
1Ca                         1Ca
2F                           2Br
This is balanced.
