How many moles of ZnCl2 will be produced from 23.0 g of Zn,

assuming CuCl2 is available in excess?

Zn + CuCl2 ZnCl2 + Cu

 

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

 

Zn의 몰질량 = 65.38 g/mol

23.0 g / (65.38 g/mol) = 0.351790 mol Zn

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

 

 

Zn : ZnCl2 = 1 : 1 계수비(몰수비) 이므로,

0.351790 mol Zn = 0.351790 mol ZnCl2

 

 

: 0.352
