what mass fructose is needed to prepare 400ml of a 150mM solution?

Solutions

Expert Solution

molar mass of fructose = 180.16 g

From definition,

To prepare 1000 mL of 1 M solution mass of fructose needed = 180.16 g

To prepare 400 mL of 1 M solution mass of fructose needed             = 180.16 * 400/1000 g

To prepare 400 mL of 150*10-3 M solution mass of fructose needed = 180.16 * 400 * (150*10-3)/1000 g

                                                                                                            = 10.8096 g
