In my bio lab we are creating serial disk dilutions (100mg, 300mg, 500mg) from a plant extraction sample. Wood sample #1 (7mL of hexane) Hexane 0.6651g so .6651g of the plant was dissolved in 7mL of hexane. Then I did dilution calculations so 0.6551g/7 mL = 0.095g/ml so I assumed 10mL of 100mg/L 10ml x .1g/mL= 1 g vmL x .095g/mL= 1 g vmL= 10.52 mL so I assumed 10mL of 300mg/mL 10ml x .3g/ml= 3g vmL x .095g/mL= 3g VmL= 31.57 mL so I assumed 10mL of 500mg/mL 10 mL x .5g/mL =5 g 10mL x .095g/mL = 5g VmL= 52.6 mL Please let me know where I am going wrong if you a problem. I appreciate the help. Thank you.
