If the partial pressure of carbon dioxide is 30torr at STP, and nitrogen is the only other gas present, what is the percent by mass of carbon dioxide?
Approach
Pressure=760 torr
PpCO2=30 torr
PpN2=730 torr
percent by mass = mass of CO2/total mass of gas
The book explains to find mole fraction by taking 30/760 to get 0.004 by I don't get how 30torr=30 moles of gas? Could someone explain the steps and how to approach this problem. This is not clicking.
