Asked by Ujjwal Kumar | 06 Oct, 2010, 10:40: AM
Expert Answer
According to stoichometry,
 
1 mole of Zn will give 2 mole of HCl
 
and, .2 mole of Zn is given.
 
Hence, moles of HCl will be .2/2=.1 moles of HCl
 
Number of Moles=wt/mol. wt
 
.1=wt of HCl/MOl.wt of HCl
 
.1=wt of HCl/36.5
 
wt of HCl =3.65 g

and,  60% of HCl is=2.19 g
 
We know that,
 
1 mole of gas has 22.4 L Volume
 
Here,
 
According to stoichometry,
 
1 mole of Zn will give 1 mole of H2
 
Hence, . 2 moles of H2
 
means, .2*22.4 L=4.48 L of H2
