Answer 2

The required value of x = 5

GIVEN: Na2CO3 has water of crystallization and its formula is Na2CO3 xH20. If 2.32 g of Na2CO3-XH20 is heated then it loses 1.26 g of water
TO FIND: The value of x used in the equation
SOLUTION:

As we are given in the question,

Mass of hydrous given in the question =2.32g

Mass of anhydrous given in the question =1.26g

As we know,

Crystallization refers to the process through which a solid forms, where the atoms of the particles or molecules are highly organized and tightly packed into a structure known as a crystal.

The formula for crystallization,

Na2CO3.xH2O=106+18X

2.32/1.26=106+18X/106

1.26(106+18X)=246

106+18X=195

18X=89

X=5 (approx)

Therefore, the required value of x according to the question is 5.
