# What is the partial pressure of the NH3

## Homework Statement

The combined pressure of 32.0 g of CH4, 64.2 g NH3, and 100 g of CO2 is 9.42 atm. What is the partial pressure of the NH3

## Homework Equations

Dalton's Law of Partial Pressure = P=Pa +Pb + Pc ...
The individual partial pressure follow the ideal gas law. For component A, (Pa)V=(nA)RT where nA is the number of oles in component A

## The Attempt at a Solution

I have converted all the grams to moles by dividing the grams by the compounds molar mass. I have no idea what to do from there. Someone please help.

$\frac{n_{NH_3}}{n_{total}}.(9.42)$
