Answer:

D

Explanation:

First you multiply 4.65 with 21.82 to get the mols of hcl, which is 101.463. Then you make an ice table. The ice table should look like this:

HCl       +  NaOH     =  12NaCl + H2O

101.463   6.022e23   1.989e30

As the ice table above shows, you will have 1.989e30 mols of nacl after the reaction. With that information, you can then divide it by 2.833333333333333e30 to get 0.702 M.
