Answer:
The new molarity is 0.614 M
Explanation:
Formula for dilutions is:
M concentrated . Volume of conc = Volume of dil . M diluted
6.54 M . 249 mL = 416 mL . M diluted
Notice that volume of diluted is = Initial volume + What we added of water
(249mL + 167 mL)
(6.54 M . 249 mL) / 416mL = M diluted → 0.614 M
Group 1 & Group 2 contains only metals
Hope this helps!
I think it is
