To find the percent (m/v) of the solution, we need to first find the mass of the drug in grams that is dissolved in the final volume of the solution.
We can start by using the information given to find the concentration of the drug in the solution:
Concentration = amount of drug / volume of solution
3.00 mL = 2.00 mL + volume of powder drug
Volume of powder drug = 3.00 mL - 2.00 mL = 1.00 mL
Concentration = 4.00 g / 1.00 mL = 4.00 g/mL
Now we can use the concentration and the final volume of the solution to find the mass of the drug in grams that is dissolved in the final volume:
Mass of drug = concentration x volume of solution
Mass of drug = 4.00 g/mL x 3.00 mL
Mass of drug = 12.00 g
Finally, we can calculate the percent (m/v) of the solution:
Percent (m/v) = mass of drug / volume of solution x 100%
Percent (m/v) = 12.00 g / 3.00 mL x 100%
Percent (m/v) = 400%
Therefore, the percent (m/v) of the solution is 400%. This is a higher than usual value and may be due to an error in the measurements or calculations.
Al pharmacist adds 2.00 mL of distilled water to 4.00 gram of powder drug. The final volume of the solution is 3.00. Ml .What is the percent ( m/v) of the solution?
