#"Concentration"# #=# #"Moles of solute"/"Volume of solution"# #~=# #1.7*mol*L^-1#.

Explanation:

#"Moles of solute"# #=# #"Volume"xx"Concentration"#

#"Final concentration"# #=# #"Total moles of solute (moles)"/"Final volume of solution (Litres)"# #=#

#(65.0xx10^-3Lxx0.513*mol*L^-1+140.0xx10^-3Lxx2.33*mol*L^-1)/((65.0+140.0)xx10^-3*L)#

#~=# #1.7*mol*L^-1# with respect to glucose.
