question

Assume that all gases are perfect and that data refer to 298.15 K unless otherwise stated. Calculate the total change in entropy, when a sample of nitrogen gas of mass $14 \mathrm{~g}$ at $298 \mathrm{~K}$ and 1.00bar1.00 \mathrm{bar} doubles its volume in an isothermal irreversible expansion against pex=0p_{\mathrm{ex}}=0.
Plain-text mathematical notation (without MathML)
Assume that all gases are perfect and that data refer to 298.15 K unless otherwise stated. Calculate the total change in entropy, when a sample of nitrogen gas of mass $14 \mathrm{~g}$ at $298 \mathrm{~K}$ and 1.00bar doubles its volume in an isothermal irreversible expansion against p_(ex)=0.
