How many moles of Hg will be produced from 34.0 g of HgO

How many moles of Hg will be produced from 34.0 g of HgO?

2HgO → 2Hg + O2

 

-----------------------------------------

 

HgO의 몰질량 = 216.59 g/mol

34.0 g / (216.59 g/mol) = 0.156979 mol HgO

( 계산 설명 http://ywpop.tistory.com/7738 )

 

 

HgO : Hg = 1 : 1 계수비(몰수비) 이므로,

0.156979 mol HgO = 0.156979 mol Hg

 

 

답: 0.157
