Answer to Question #237511 in General Chemistry for zac

Question

Determine the volume of Cu(NO3)2 stock solution and volume of H2O needed to make 10.00 mL of four solution with concentrations between 0.40 M and 0.025 M. 

Answer 1

0.200 M – 9.375 ml of 0.40 M + 9.375 ml of distilled water

↓ 8.75 ml

0.100 M – 8.75 ml of 0.200 M + 8.75 ml of distilled water

↓ 7.5 ml

0.050 M – 7.5 ml of 0.100 M + 7.5 ml of distilled water

↓ 5 ml

0.025 M – 5 ml of 0.050 M solution + 5 ml of distilled water
