A balloon is filled to a volume of 1.50 L with 3.00 moles of gas at 25 °C. With pressure and temperature held constant, what will be the volume (in L) of the balloon if 0.50 moles of gas are released?

Volume : 1.25 L

Explanation:

We are given here that the volume ( V ) = 1.50 Liters, the initial moles ( held at 25 °C ) = 3.00 mol, and the final moles ( n ) = 3.00 - 0.5 = 2.5 mol. The final mol is calculated given that 0.50 mol of gas are released from the prior 3.00 moles of gas.

Volume ( V ) = 1.50 L,

Initial moles ( n ) = 3.00 mol,

Final Volume ( n ) = 3.00 - 0.5 = 2.5 mol

Applying the combined gas law, we can calculate the final volume ( V ).

PV / nT = PV / nT - we know that the pressure and temperature are constant, and therefore we can apply the following formula,

V / n = V / n - isolate V,

V = V n / n = 1.50 L 2.5 mol / 3.00 mol = ( 1.5 2.5 / 3 ) L = 1.25 L

The volume of the balloon will be 1.25 L.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
