Question

PLEASE HELP ME ASAP PLEASE!!!

A sealed vessel, containing nitrogen dioxide and carbon dioxide gases has a total pressure of 2558 psi.

What is the partial pressure of nitrogen dioxide (in psi) if the partial pressure of carbon dioxide is 795 psi?​

Answer 1

1763psi

Step-by-step explanation:

Answer 2

`\large \boxed{\text{1763 psi}}`

Step-by-step explanation:

We can use Dalton's Law of Partial Pressures:

Each gas in a mixture of gases equals its pressure independently of the other gases

`\begin{array}{rcl}p_{\text{NO2}} + p_{\text{CO2}} & = & p_{\text{tot}} \\p_{\text{NO2}} + \text{795 psi} & = &\text{2558 psi}  \\p_{\text{NO2}} & = &\text{2558 psi - 795 psi} \\& = & \textbf{1763 psi}\\\end{array}\\\text{The partial pressure of nitrogen dioxide is $\large \boxed{\textbf{1763 psi}}$}`
