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:

Total body clearance of this drug:

The total body clearance of this drug is 22.5 L/hr.
Answer:
The correct answer is 5s
Explanation:
Strontium atomic number = 38
Electronic configuration is 
As
orbital is valence orbital in strontium, the outer electrons exists in that orbital only.
Explanation:
According to the psychrometric chart at dry bulb temperature of
and RH 70%, the absolute humidity = 0.011 kg/kg dry air
Formula to calculate humid volume is as follows.
dry air = 
= 
= 
= 0.847
dry air
Hence, humid volume of air is 0.847
dry air.
Specific enthalpy of dry air = specific heat capacity of dry air × dry bulb temperature
=
= 21.126 kJ/kg dry air
Hence, the specific enthalpy of the air is 21.126 kJ/kg dry air.
As per the psychrometric chart at given conditions wet bulb temperature = 17.5 
As per the psychrometric chart at given conditions dew point temperature = 15.5
