Explanation:
Given that:
The heat of combustion of methylhydrazine = 
It means that:
1 mole of methylhydrazine on combustion, releases
of energy
Molar mass of methylhydrazine = 46.072 g/mol
Means that, 1 mole of methylhydrazine contains 46.072 g of methylhydrazine
Thus,
46.072 g of methylhydrazine on combustion, releases
of energy
Also,
1 g of methylhydrazine on combustion, releases
of energy
206.2 g of methylhydrazine on combustion, releases
of energy
Heat released =
