Answer:

The correct answer is option B.

Explanation:

Concentration of a  steady-state plasma ,= 25 mg/L

Weight of the volunteer =75 kg

Rate of infusion = 7.5 mg/kg hr

Concentration of steady-state plasma in 75 kg weight body:

7.5 mg/kg hr\times 75 kg=562.5 mg/hr

Total body clearance of this drug:

\frac{562.5 mg/hr}{25 mg/L}=22.5 L/hr

The total body clearance of this drug is 22.5 L/hr.

11Alexandr11 [23.1K]

The liquid that is been dispensed during titration as regards this question is Titrant.

  • Titration can be regarded as  common laboratory method that is been carried out during quantitative chemical analysis.
  • This analysis helps to know the concentration of an identified analyte.
  • Burette can be regarded as laboratory apparatus.

It is used in the in measurements of variable amounts of liquid ,this apparatus helps in dispensation   of liquid, especially when performing titration.

  • The specifications is been done base on their volume, or resolution.
  • The liquid that comes out of this apparatus is regarded as Titrant, and this is gotten during titration process, which is usually carried out during volumetric analysis.

Therefore, burrete is used in volumetric analysis.
