Given the following, what would the new volume of the balloon be?

Question

A child has a toy balloon with a volume of 1.80 liters. The temperature of the balloon when it was filled was 20° C and the pressure was 1.00 atm. If the child were to let go of the balloon and it rose 3 km into the sky where the pressure is 0.667 atm and the temperature is -10° C.....

$V_2~=2.5*L$

The combined gas equation holds that for constant $n$ :

$(P_1V_1)/T_1 = (P_2V_2)/T_2$

Thus $V_2$ $=$ $(P_1xxT_2xxV_1)/(P_2xxT_1)$ (this clearly has the units of volume.)

$=$ $(1*atmxx263*Kxx1.80*L)/(0.667*atmxx293*K)$ $=$ $??L$
