A patient is prescribed 5mg/kg of a medication. The patient weighs 8.1Kg. The medication is supplied in a solution containing 200mg in 5mL. a) Calculate the dosage of the drug to be given b) Calculate the volume of the solution to be given

A drug is supplied as a solution of 100. mg/mL. If 2.0 mL of this concentrated drug solution is diluted to a volume of 25.0 mL, how much of the diluted solution should be administered to supply a dose of 150 mg?    (Use two types of problems in this problem.)     0.053 mL     8.0 mL     7.5 mL     19 mL     0.13 mL

A medical solution had a concentration of 30mg/ml. How many ml would need to be delivered to dispense a total of 150 mg of med?

How many milliliters of 25.0 mg/L stock solution must be added to a 25.00-mL volumetric flask to produce a 20.0 mg/L solution? Report your answer in decimal form (not scientific notation) with correct sig figs and including one space followed by your units.

*Density of toluene 0.86g/mL Calculate the volume of toluene needed to make 50 mL of a 780 micrograms /mL solution. Round to the nearest microliter.

What is the concentration of the AR stock solution in ppm? Using the molar mass of AR (496.42 g/mol), and that 1 ppm = 1 mg/L, convert this ppm concentration to μM. Assume the density of the solution is 1.000 g/mL. Concentration of AR Stock Solution (ppm) Concentration of AR Stock Solution (μM) 21.22 Unrounded 3 Rounded 3

If a total of 125 mL of a 10% solution is diluted to 500 mL in a 500-mL volumetric flask, what is the concentration of the resulting new solution?   You are asked to make a 1/2 dilution using 1.5 mL of serum. How much diluent do you need to use?  If you make a five-tube twofold dilution using 2 mL of serum, what is the concentration of serum in tube #4?
