If I boil the water until the volume of the solution is 250 mL, what will the molarity of the solution be? Dilutions Worksheet 1) If I have 340 mL of a 1.5 M NaBr solution, what will the concentration be if I add 650 mL more water to it? 2) If I dilute 250 mL of 0.50 M lithium acetate solution to a volume of 550 mL, what will the concentration of this solution be? 3) If I leave 750 mL of 0.75 M sodium chloride solution uncovered on a windowsill and 250 mL of the solvent evaporates, what will the new concentration of the sodium chloride solution be? 4) To what volume would I need to add water to the evaporated solution in problem 3 to get a solution with a concentration of 0.50 M? 5) If I add 125 mL of water to 125 mL of a 0.15 M NaOH solution, what will the molarity of the diluted solution be? 6) If I add water to 150 mL of a 0.15 M NaOH solution until the final volume is 350 mL, what will the molarity of the diluted solution be? 7) How much 0.05 M HCl solution can be made by diluting 250 mL of 10 M HCl? 8) I have 345 mL of a 1.5 M NaCl solution. If I boil the water until the volume of the solution is 200 mL, what will the molarity of the solution be? 9) How much water would I need to add to 500 mL of a 2.4 M KCl solution to make a 1.0 M solution? Dilutions Worksheet Solutions 1) If I have 340 mL of a 0.5 M NaBr solution, what will the concentration be if I add 560 mL more water to it? 0.19 M (the final volume is 900 mL, set up the equation from that) 2) If I dilute 250 mL of 0.10 M lithium acetate solution to a volume of 750 mL, what will the concentration of this solution be? 0.033 M (the final volume is 750 mL, set up the equation from that. Note that the phrasing difference between problems 1 and 2 makes a big difference in the final answer). 3) If I leave 750 mL of 0.50 M sodium chloride solution uncovered on a windowsill and 150 mL of the solvent evaporates, what will the new concentration of the sodium chloride solution be? 0.63 M (this is the opposite of a dilutions problem the V2 value is smaller than V1, but otherwise the equation is no different.) 4) To what volume would I need to add water to the evaporated solution in problem 3 to get a solution with a concentration of 0.25 M? 1500 mL      Home / % u  ( G H I N O Q R : N O °ӡzlllZ#hshs5CJOJQJ^JaJ$hsCJOJQJ^JaJ$hsOJQJ^JaJ$hs5CJ$OJQJ^JaJ$hsCJOJQJ^JhshsCJOJQJ^J#hshP5CJOJQJ^JaJ$ hshPCJOJQJ^JaJ$ hshsCJOJQJ^JaJ$hPOJQJ^JaJ$hP5CJ$OJQJ^JaJ$#  M N O P Q R S 0^`0gds 0^`0$a$ : N O A B C gds$a$gds 0^`0gds1QCDul3#˼{wowowowowjhPUhP1jhP5CJOJQJU^JaJ$mHnHuhP5H*OJQJ^JaJ$hP5OJQJ^JaJ$hPOJQJ^JaJ$hP5CJ$OJQJ^JaJ$ hshPCJOJQJ^JaJ$hshsCJhsCJOJQJ^JhshsCJOJQJ^J*uvwxk2#$% 0^`0$a$ 0^`0gds 0^`0hPhPCJ4OJQJ,1h/ =!"#$% ^ 666666666vvvvvvvvv666666>6666666666666666666666666666666666666666666666666hH6666666666666666666666666666666666666666666666666666666666666666662 0@P`p2( 0@P`p 0@P`p 0@P`p 0@P`p 0@P`p 0@P`p8XV~_HmH nH sH tH @`@ NormalCJ_HaJmH sH tH R@R  Heading 1dd@&[$\$5CJ0KH$\aJ0DA`D Default Paragraph FontVi@V 0 Table Normal :V 44 la (k ( 0No List 4 4 Footer  !4@4 s0Header  H$6/6 s0 Header CharCJaJH@"H s0 Balloon TextCJOJQJ^JaJN/1N s0Balloon Text CharCJOJQJ^JaJPK![Content_Types].xmlN0EH-J@%ǎǢ|ș$زULTB l,3;rØJB+$G]7O٭V$ !)O^rC$y@/yH*񄴽)޵߻UDb`}"qۋJחX^)I`nEp)liV[]1M<OP6r=zgbIguSebORD۫qu gZo~ٺlAplxpT0+[}`jzAV2Fi@qv֬5\|ʜ̭NleXdsjcs7f W+Ն7`g ȘJj|h(KD- dXiJ؇(x$( :;˹!
