HARDEST QUESTION OF ALL TIME CAN YOU SOLVE IT? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The pressure in an automobile tire filled with air is 245.0kPa. If PO2 = 51.3kPa, PCO2 = 0.10kPa, and Pothers = 2.3kPa, what is PN2 ?

Answer 1

Answer:

PN2 = 191.3kPa

Step-by-step explanation:

Ptotal = PO2 + PCO2 + PN2 + Pothers = 245.0kPA

Work backwards to find PN2

245.0kPA - PO2 - PCO2 - Pothers = PN2

245.0kPA - 51.3kPa - 0.10kPa - 2.3kPa = PN2

245.0 - 51.3 = 193.7

193.7 - .10 = 193.6

193.6 - 2.3 = 191.3
