Answer
The moles of O2 in the sample = 4.71 mol
Explanation
Given:
Temperature, T = 294 K
Pressure, P = 3.55 atm
Volume, V = 32.0 L
The ideal gas constant, R = 0.0821 L*atm/mol*K
What to find:
The number of moles, n of O2 in the sample.
Solution:
The number of moles, n of O2 in the sample can be calculated using the ideal gas equation.
[tex]\begin{gathered} PV=nRT \\ \\ \Rightarrow n=\frac{PV}{RT} \end{gathered}[/tex]Plugging the values of the parameters into the formula, we have;
[tex]n=\frac{3.55atm\times32.0L}{0.0821L*atm/mol*K\times294K}=4.71\text{ }mol[/tex]The number of moles, n of O2 in the sample = 4.71 mol
