ANSWER NEEDED ASAP
At a festival, spherical balloons with a radius of 270 cm are to be inflated with hot air and released. The air at the festival will have a temperature of 25 c and must be heated to 100 c to make the balloons float. 3.00kg of propane fuel are available to be burned to heat the air. Calculate the maximum number of balloons that can be inflated with hot air.
specific heat capacity of air = 1.009 J/g c
density of air at 100 c = 0.946 kg/m^3
density of propane at 100 c= 1.440 kg/m^3
formation enthalpy of propane at 25 c =-103.85 kJ/mol
