Question

Plzz solve the problem as discussed above the photo​

Answer 1

The given change is as follows:

MBr  

x

​  

+XHCl→MCl  

x

​  

+XHBr

For the given reaction:

Equivalent of MBr  

x

​  

 =  Equivalent of MCl  

x

​  

 

E+80

1.878

​  

=  

E+35.5

1.0

​  

 

∴ Equivalent mass of the metal (E)=15.18

Now, atomicmass×specificheat≃6.4

∴atomicmassofmetal=  

0.14

6.4

​  

=45.71

∴ Valency of metal =  

Eq.mass

Atomicmass

​  

=  

15.18

45.71

​  

=3.01=3(∵integer)

∴Exactatomicmassofmetal=15.18×3=45.54

PLS MARK ME AS BRAINLIEST

∴ Molar mass of  MBr  

x

​  

 or MBr  

3

​  

(x=3)=45.54+80×3=285.54gmol  

−1

 

So, the nearest integer is 286.
