Answer:

So the math expression is  

             $heat = \frac{ 35. 7 KJ * 1900 \ gram }{ 1 \ gram }$

Explanation:

From the question we are told that

  The heat released for 1 gram of reactant consumed is  $H = 37.5 \ KJ/g$

   The mass of reactant considered is  $m = 1.9 \ kg = 1900 \ g$

So  if

             $37.5 \ KJ$ is produced for  1 gram

Then

              x kJ is produced for  1900 g  

=>   $x = \frac{ 35. 7 KJ * 1900 \ gram }{ 1 \ gram }$

So the heat released is  

       $heat = \frac{ 35. 7 KJ * 1900 \ gram }{ 1 \ gram }$
