6.Heat=ms
S of Mg=1.020kj/mol and s of MgO=0.88kj/mol
Heat of Mg=1.8564 kJ Heat of MgO=6.8351kJ
7.
is as same as heat from the law of thermodynamics
8.Given molarity and volume,number of moles can be calculated.
Number of moles=volumexmolarity=0.1x1=0.1.Here 100g can be taken as 0.1l.
9.
for Mg=18.564 and for MgO=68.351
