Calculate the volume of gas at 1.25 atmosphere, if volume occupied by gas at 1 atmosphere and at same temperature is 25 mL .
  1. 15 mL
  2. 20 mL
  3. 25 mL
  4. 35 mL

Solution

According to Boyle's law, $P_1 V_1=P_2 V_2$ (at constant n and T) $\therefore \quad \mathrm{V}_2=\frac{\mathrm{P}_1 \mathrm{~V}_1}{\mathrm{P}_2}=\frac{1 \mathrm{~atm} \times 25 \mathrm{~mL}}{1.25 \mathrm{~atm}}=20 \mathrm{~mL}$
