A 500 mg vial of Kefzol needs to be reconstituted to a final concentration of 275 mg/mL. Assuming the Kefzol powder adds 0.2 mL of volume, how much sterile water do you add to achieve this concentration?

I have: DMEM:F12 800X ITS 1.07 g/ml Linoleic acid Nu-serum (pure solution) BSA (pure powder)   How much of each would I need to make 500ml of (1x ITS, 7.49 ug/ml linoleic acid, 4% v/v Nu-serum, 0.15% W/V BSA, and DMEM:F12 as the solvent)?

A vial of Doxorubicin reads 0•5g per vial. Instructions say to reconstitute each 12mg with 2•5ml of NS. How many ml of NS will be needed to reconstitute the vial of the recommended concentration? please show working

Lipids from an organic sample are extracted separately by column chromatography using the ff eluants: 1st eluant - chloroform: methanol: water (6:3:1) 2nd eluant - methanol: chloroform (9:1) 3rd eluant – petroleum ether: ethyl ether (1:1) Test results for each eluate are tabulated below. Identify the possible lipid present in each eluate. Test Reagents 1. KHSO4 2. HNO3,(NH4)3MoO4 3. CHCl3, acetic anhydride, conc. H2SO4 4. -naphthol, conc. H2SO4 5. Hydroxylamine HCl, FeCl3 6. ninhydrin reagent POSSIBLE LIPIDS: Triacylglycerol, cholesterol, sphingomyelin, lecithin

A patient is to receive Tazidine by intramuscular injection.  A 10.0-mL vial contains 1 gram of dry powder that was reconstituted with 3 mL of sterile water.  The reconstituted solution contains 340 milligrams Tazidine in 1.00 mL of volume.  How much solution should be injected if a patient needs to receive a 0.30 gram dose?  Enter the numerical part of the answer in the first box (using correct significant figures) and the correct unit in the second box.

The doctor ordered Oxacillin 650mg every 6 hours.  The instructions on the 2gm vial states to reconstitute with powder with 11.5ml of sterile water for injection, yielding 220mg/1.5ml. How many ml will you administer? using dimensional analysis and show work

How do you make 70 ml of a 60% solution??

If I am making 500ml of a solution with 0.625ml ITS, 0.0035ml Linoleic acid, 20ml Nu-serum, 0.75g BSA, and DMEM:F12 as my solvent, how best would I make this solution and what tools would be the most accurate to use?

A student needs 240 mL of a 1/20 dilution of an undiluted stock solution. What volume (mL) of the stock solution will be required? Note: Your answer should be in numerical format to the nearest whole number (with a decimal).
