mansi the question is very simple u have to use the formula H=E+ngRT  ng represents the change in number of moles of the gaseous species
thus substitute the values and you will get the answer here ng =1

see akshat and ng29 if i take value of R as 8.313 than
H=E+ngRT
176=E+1x8.313x1240
176-10308.12=E
E=-10132.12 which can’t be possible so what’s the correct method and answer....
