<span>Moles = weight in g / atomic weight So, moles in 40 g of He = 40 / 4 = 10 moles.</span>
Answer : The volume of the balloon will be, 0.494 liters
Solution :
Charles' Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
or,
where,
= initial volume of gas = ?
= final volume of gas = 0.54 L
= initial temperature of gas = 273.15 K
= final temperature of gas = 298.5 K
Now put all the given values in the above equation, we get the initial volume of balloon.
Therefore, the volume of the balloon will be, 0.494 liters
