[tex]FeS_{(s)} + 2HCl_{(aq)} \rightarrow FeCl_{2(aq)} + H_{2}S_{(g)}

[/tex]

[tex]H^{\circ}_{f}[/tex]values in kilojoules per mole:

[tex]HCl_{(g)} = -93[/tex]

[tex]FeS_{(s)}=-95[/tex]

[tex]H_{2}S_{(g)} = -20[/tex]

[tex]FeCl_{2(s)} = -341[/tex]

[tex]H_{sol}[/tex] values in kilojoules per mole:

[tex]HCl_{(g)} = -74[/tex]

[tex]FeCl_{2(s)} = -79[/tex]

How much heat will be evolved in making 15.2g of [tex]H_{2}S_{(g)}[/tex] at STP from [tex]FeS_{(s)}[/tex] and dilute [tex]HCl_{(aq)} ?[/tex]

2. Relevant equations

How do I calculate the heat evolved? I know its pretty useless to calculate the heat of reaction for this entire reaction because i have heats of solution instead. So what can i do ?
