We are also given that we are adding 1000 mL of distilled water to the initial solution, so the final volume is 500 mL + 1000 mL = 1500 mL. We can plug in the known values for C1, V1, and V2 into the dilution formula and solve for C2: Therefore, the concentration of the diluted solution is 1 mol/L. trailer << /Size 38 /Info 6 0 R /Encrypt 20 0 R /Root 19 0 R /Prev 58285 /ID[<9c22a42be68ddddc6f1a0f5b5826fbe6><9c22a42be68ddddc6f1a0f5b5826fbe6>] >> startxref 0 %%EOF 19 0 obj << /Type /Catalog /Pages 7 0 R /OpenAction [ 21 0 R /XYZ null null null ] /PageMode /UseNone /JT 17 0 R /PageLabels 5 0 R >> endobj 20 0 obj << /Filter /Standard /R 2 /O ( UV.`Dz-#_m_}g) /U (}d\\Oe[\)\\0?Af=-G) /P -60 /V 1 >> endobj 36 0 obj << /S 45 /L 100 /Filter /FlateDecode /Length 37 0 R >> stream Saved 0000002138 00000 n you want to find the required volume Write the Expression. 1, Then it is studied unde SpaceDuck saved 0000002138 00000 n / ; /metadata Adobe InDesign 7.5 hospice.
