I don'know,but you should do somthing to solve your question.
Magnesium plus chlorine equals to magnesium chloride
The mass of a molecule is very very small but there is many molecules and they all have kinetic energy. First, we have to assume that the gas is ideal. Kinetic energy of an ideal gas is only a function of moles and temperature. Hence:
KE=(3/2)nRT = (3/4)(1mole)(8.314J/molK)(25+273.15)K
= 3718.22J or 3.7KJ
