if potassium chloride elixir has a concentration pf 10%w/v, how many milliliters are needed to provide a patient with 18 meq of potassium

A doctor orders 230. mL of 1 % (m/v) ibuprofen. If you have 10. % (m/v) ibuprofen on hand, how many milliliters do you need?

Mountain Dew® contains caffeine, C8H10N4O2, at a concentration of 0.7838 mM and has a density of 0.998 g/cm3. (a) What is the concentration of caffeine in units of % by volume (w/v)?(b) What is the concentration of caffeine in units of % by mass (w/w)?(c) Compare you answers from (a) and (b). You should not be surprised if they are similar because % by mass and % by volume are the same if the density of the solution were exactly 1 g/cm3.

Normal saline solution used in IVs is usually around 0.90% m/v or 0.154 M; however, other saline solutions may have a higher or lower concentration of sodium chloride, NaCl, depending on the use. For example, a hypertonic saline solution with a concentration greater than 0.154 M may be used to treat hyponatremia (sodium concentration in the serum is too low). Calculate the molarity of the NaCl solution when 43.8 g of NaCl is dissolved in 100 mL of water. Express the molarity with the appropriate units. • View Available Hint(s) HA Value Units Submit

Too much manganese in drinking water can cause the following undesirable effects: black to brown color; black staining; bitter metallic taste . The EPA's Secondary Maximum Contaminant Level for manganese in drinking water is5.00×10-2 mg/L.(1) If 1.52×104 liters of water in a storage tank contains 1.08 grams of Mn , what is the contaminant level in ppm? ppm      Assume that the density of the impure water is 1.00 g/mL.(2) Is this level acceptable based on EPA guidelines?

How many milliliters of a 0.900%0.900% (m/v) normal saline solution can be prepared from 3.003.00 g of sodium chloride, NaClNaCl? Note that mass is not technically the same as weight, but the abbreviation % (w/v) is often used interchangeably with % (m/v).

The recommended dose of Remdesivir is 200 mg (0.200 grams) by injection on day 1. Assuming the blood volume of the average adult is 5 liters, and the molecular weight of Remdesivir is 602.56 g/mole, what is the molarity of Remdesivir in moles/liter?   The recommended dose of Remdesivir is 200 mg (0.200 grams) by injection on day 1.
