ANSWER:Step 1 of 2
a.)
We have to find a real problem for which the given equation is the correct equation.
\(n\) moles of an ideal gas in a cylinder is expanded to a third of its initial volume at a constant temperature of \(77^{\circ} \mathrm{C}\), work done is \(50 \mathrm{~J}\). Find the number of moles of gas in the cylinder?
