Solved 1. A laboratory is testing the concentration level in

A laboratory is testing the concentration level in milligrams per milliter for the active ingredient found in a pharmaceutical product. In a random sample of five vials of the product, the concentrations were measured at 2.46, 2.57,2.70, 2.64 and 2.54 mg/ml. (a) Determine a 95% confidence interval for the mean concentration level in milligrams per

Dose Calculation Desired Over Have Formula Method

Jun 20, 2023 · The clinician has 2 mg/mL vials in the automated dispensing unit. How many milliliters are needed to arrive at an ordered dose? The desired dose os placed over 1 remember, (x mL) = 4 mg/1 x 1 mL/2 mg x (4)(1)/2 x 4/2 x 2/1 = 2 mL, keep multiplying/dividing until the desired amount is reached, 2 mL in this example.

Using units to solve problems: Drug dosage - Khan Academy

Your numerator is 75*4*10*5mg*doses*days*ml. Your denominator is 250*dose*day*mg. The words dose*day*mg in both the numerator and denominator cancel out giving the answer in ml. and the numbers 75*4*10*5/250 = 15000/250=60. So the answer is 60ml. I hope that helps make it click for you.
