five gases combined in a gas cylinder have the following partial pressures: 3.00 atm (\text{n}_2), 1.80 atm (\text{o}_2), 0.29 atm (\text{ar}), 0.18 atm (\text{he}), and 0.10 atm (\text{h}). what is the total pressure that is exerted by the gases?
use p_t = p_1 + p_2 + p_3 + \dots + p_n.

5.08 atm
5.19 atm
5.27 atm
5.37 atm
