Answer:

Approx. #0.13*mol*L^-1#

Explanation:

#"Concentration"# #=# #"Number of moles"/"Volume of solution"#.

Initially, we have #0.295*Lxx1.00*mol*L^-1# #NH_4Cl# #=# #??*mol#

Finally this molar quantity is dissolved in a #2.25*L# volume.

#"Concentration"# #=# #(0.295*Lxx1.00*mol*L^-1)/(2.25*L)# #=# #??mol*L^-1#
