The heat of combustion of hydrogen (the energy released by burning hydrogen with oxygen) is 1.43�108j/kg. what mass of hydrogen would have to be burned in the sun in one second to release the same amount of energy (i. e., generate the same power) as is released by fusion?

the net reaction for the proton-proton chain is
411h \rightarrow24he + 2\beta+

to find the energy released by this reaction, you will need the following mass data:
mass of 11h=1.007825u and mass of 42he=4.002603u.

the total energy q released in a single fusion reaction event for the equation given in the problem introduction = 4.30�10? 12 j

the power radiated by the sun is about 4�1026w. the number of proton-proton chain fusion reactions in one second = 9.24�1037
mass of hydrogen converted into helium by the fusion reactions in one second = 6.20�1011 kg
