Question

a perfect elastic balloon filled with helium gas has a volume of 1.25×10³ dm³ at 1.000 atm and 25°C on ascending to a certain altitude where temperature is 15°C the volume of the balloon becomes 1.208×10³dm³ show that this data satisfy Charles law​

Answer 1

Answer:

Using PV=nRT formula

2×10−3×105=n×8.314×268

n=0.1

weight=n×  gram molecular weight of He

weight=0.1×4=0.4 grams.
