How moles are present in 0.5 moles of a mercury in stp

i think the ques u asked is wrong as its the no of molecule present and not the moles .
i am assuming it to be molecule here ,
the molar mass of hg is 200 U
which means 1 mole of hg = 200 g
1 mole = 200 g
0.5 mole = 200 *0.5 = 100 g
hence , the mass of 0.5 mol of hg is 100g
1 mole = 6.022 * 10 ^ 23 molecules of hg
so, 0.5 moles = 0.5 * 6.022*10^23= 3.011*10 ^ 23
HOPE IT CLEARS NOW ..
