In a basal metabolism measurements timed at 6.0 minute a patient exhaled 52.5 litre of air measured over water at `20^(@)C` The vapour pressure of water at `20^(@)C` is 17.5 torr The barometric pressure was 750 torr. The exhaled air analysed 16.75 volume per cent of oxygen and inhaled air 20.32 percent oxygen, both on a dry basis Neglecting any solubility f the gases in water and any difference in the total volume of inhaled and exhaled air, calculate rate of oxygen consumption by the patient in mL `(STP)` per minute

Answer

`0279`
