225 grams of #NH_4NO_3# in 2.5 liters of water has what concentration?

Answer 1

#"Concentration"="Moles of solute"/"Volume of solution"#

Following the above definition, and assuming (reasonably) that the volume does not markedly change upon dissolution of the solute:

#"Concentration"# #=# #(225*cancelg)/(80.04*cancelg*mol^-1)xx1/(2.5*L)# #~=# #1.1*mol*L^-1#.
