Answer to Question #98637 in Organic Chemistry for John

Question

is the solution which contains 0.3 m of hno3 3. is a solution containing 2.22 g of x (oh) 2 250 cm cube of solution. during titration 19.0 cm cube of a completely neutralise 25.0 cm cube of bcalculate the molar mass of x (oh)2

Answer 1

M(X(OH)₂)=m(X(OH)₂)*2*1000/(V(HNO₃)*C(HNO3))=2.22*2*100/(19*0.3)=78 (g/mol)

Answer: 78 g/mol.
