Question

# there are different rules ofconcentration in the calculation of homeopathic medicine. Ahomeopathic doctor would like to prescribe a dose of medication toa patient. The doctor has a solution A that contains the specificdrug with a 1M concentration of a 50.0 mL solution. The doctorwould like to obtain a dose (concentration) of 12 CH units, whichis equivalent to 240 times the volume of solution A. If weknow that one mole of the original solution is used, what is thefinal concentration of the dose (solution B)? Hint: what is thefinal volume of solution B?

Explanation / Answer

For solution A volumeV1=50ml              &    molarity M1 = 1M or solution B volume V2=50X240ml              & molarityM2 = x M                                       = 12000 ml                            V1M1=V2M2 ==> M2=(V1M1/V2) =50X1/12000                                                                                    =0.004166666
