Mg(NO3)2.XH2OMg{\left({NO}_{3}\right)}_{2} . {XH}_{2}O and Ba(NO3)2.YH2OBa{\left({NO}_{3}\right)}_{2} . {YH}_{2}O, represent formula of the crystalline forms of nitrate salts. Sum of XX and YY is.......

Correct answer

6

Step-by-step solution

Magnesium nitrate crystallises with six molecules of water, whereas barium nitrate is anhydrous salts.

The hydrated form of magnesium nitrate is Mg(NO3)2.6H2OMg{\left({NO}_{3}\right)}_{2} . 6{H}_{2}O and anhydrous salt of barium nitrate is Ba(NO3)2Ba{\left({NO}_{3}\right)}_{2} respectively
∴x=6,y=0∴ x = 6, y = 0
