Suppose you have two gases numbered 1 and 2.
The total pressure can be calculated to be the ____ of the pressure of each individual gas.

Suppose you have two gases numbered 1 and 2.
Which equation represents make the most sense to calculate the total pressure exerted by both gases?
Multiply their pressures :
Ptotal = P1 × P2
Divide their pressures :
Ptotal = P1 ÷ P2
Add their pressures :
Ptotal = P1 + P2
Subtract their pressures :
Ptotal = P1 – P2
Average their pressure :
Ptotal = (P1 + P2)/2

0.90 atm
9.00 atm
920 atm
