In a hospital, an oxygen cylinder holds ...

In a hospital, an oxygen cylinder holds 10 L of oxygen at 200 atm pressure. If a patient breathes in 0.50 mL of oxygen at 1.0 atm with each breath, for how many breaths the cylinder will be sufficient. Assume that all the data is at `37^(@)C`

Text Solution

Verified by Experts

10 L at 200 atm=? L at atm (temperature remaning constant)
`P_(1)V_(1)=P_(2)V_(2)`
`200xx10=1xxV_(2)" or " v_(2)=2000" L"`
Number of breaths `=("Total volume")/("Volume consumed per breath")=(2000" L")/(0.5xx10^(-3)"L")=4xx10^(6)`
