Concentration Problems1.What mass of NaCl is needed to produce a 500 g of a 6.40% M/M solution? Get answer to your question and much more 2.What is the concentration, in g/100 mL, of a solution made by dissolving 123.2 gof phosphoric acid in 50.0 mL of solution?mL Get answer to your question and much more 3.How much water is needed to produce a 0.68 M solution of copper (I) carbonate,if 3.58 g is used? Get answer to your question and much more Moles to grams:3.58 g ÷ 187.1 g/mol = 0.019 mol Cu₂CO₃Molarity = moles ÷ LL = 0.019 mol ÷ 0.68 M= 0.028 L∴0.028 L or 28 mLwater is needed.4.What mass of carbon dioxide would you add to 1 500 L of water in order to makea 325 ppm solution? Get answer to your question and much more 5.What is the concentration of a solution made by diluting 14.0 mL of a 4.20 MNa₂CO₃to 86.0 mL? Get answer to your question and much more Cf = ( 4.2 M x 0.014 L ) ÷ 0.086 L= 0.683 M∴0.683 Mis the concentration of the solution.
