Answer:
36% m/v
Explanation:
An antibiotic solution must be prepared by diluting 100. mL of a 90. % m/v solution and bringing up the volume to 250 mL. What is the concentration of the resulting solution?
the new solution is 100/250 X 90% m/v = 36% m/v
The concentration of the resulting antibiotics solution that must be prepared by diluting 100mL of a 90. % m/v solution and bringing up the volume to 250 mL is 36% m/v.
The concentration of a solution can be calculated by using the following formula:
C1V1 = C2V2
Where;
90% m/v × 100 = C2 × 250
9000 = 250C2
C2 = 36% m/v
Therefore, the concentration of the resulting antibiotics solution that must be prepared by diluting 100mL of a 90. % m/v solution and bringing up the volume to 250 mL is 36% m/v.
