From the equation, [tex]\frac{p1 * v1}{t1} = \frac{p2 * v2}{t2}[/tex], we make v2 the subject of the formula, so that gives us: [tex]\frac{p1 * v1 * t2}{p2 * t1}[/tex]
Standard temperature = 273k
Standard pressure = 1atm
Plugging in our values, [tex]\frac{1.8 * 4.5 * 273}{1 * 140} = \frac{2211.3}{140} = 15.795 litres[/tex]
