Using Charles Law, $\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}$ $V_1/T_1 = V_2/T_2$ , the answer is 3.05 L.

Explanation:

Charles law is $\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}$ $V_1/T_1 = V_2/T_2$
first convert the temperatures to kelvin by adding 273.
22 + 273 = 295
3.5 + 273 = 276.5

substitute:
295 for $T_{1}$ $T_1$
3.25 for $V_{1}$ $V_1$
276.5 for $T_{2}$ $T_2$

$\frac{3.25}{295} = \frac{V_{2}}{276.5}$ $3.25/295 = V_2/276.5$

solve for $V_{2}$ $V_2$ (by multiplying both sides by 276.5) and the answer is 3.05 L.

Note: you can only use Charles law when the other factors, pressure and moles, are constant. If everything is changing, use the combined gas law, $\frac{P_{1} V_{1}}{T_{1}} = \frac{P_{2} V_{2}}{T_{2}}$ $(P_1V_1)/T_1 = (P_2V_2)/T_2$
