A) 6.921 g
B) 4.65 g
C) 2.925 g
D) 1.4 g
Correct Answer: C
Solution :
The reaction takes place as follows \[\underset{x}{\mathop{NaCl}}\,\,+\underset{4.9g}{\mathop{{{H}_{2}}S{{O}_{4}}}}\,\,\xrightarrow{\,}\,\underset{6g}{\mathop{NaHS{{O}_{4}}}}\,+\underset{1.825\,g}{\mathop{HCl}}\,\] According to law of conservation of mass ?mass is neither created, nor destroyed during any chemical change". \[\therefore \] mass of reactants = mass of products \[x+4.9=6+1.825\] \[x=2.925\text{ }g\]You need to login to perform this action.
