Question

A mixture of He, Ar, and Xe has a total pressure of 3.00 atm. The partial pressure of He is 0.400 atm, and the partial pressure of Ar is 0.200 . What is the partial pressure of Xe?

Answer 1

hmm challenging problem...try asking the people in Chemistry group. I'm sure you'll get a more accurate and detailed explanation there rather than in this group ^_^

Answer 2

\[p=p_{\text{He}}+p_{\text{Ar}}+p_{\text{Xe}}\]
\[p-p_{\text{He}}-p_{\text{Ar}}=p_{\text{Xe}}\]
\[3.00 [\text{atm}]-0.400[\text{atm}]-0.200[\text{atm}]=p_{\text{Xe}}\]
\[p_{\text{Xe}}=(3.00-0.400-0.200)[\text{atm}]\]
