Washing soda is a hydrate of sodium carbonate. its formula is na2co3. x h2o. Here, the value of x in the formula is 10.

We are given that:

Mass of washing soda = 2.714g

Molar mass of Na2CO3 = 105.98 g/mol

The molar mass of washing soda = (105.98 + 18x) g/mol

Solution:

The chemical equation is given below:

Na2CO3.H2Ox -------> Na2CO3 + xH2O

1 mole of Na2CO3 produces 1 mole of sodium carbonate (Na2CO3) and x moles of water.

Now number of moles of Na2CO3 = (1.006 / 105.98) = 0.009492 moles

The number of moles of washing soda is equal to the number of moles of Sodium carbonate formed i.e. 0.009492 moles

Now

2.714 / 105.98 + 18x = 0.009294

x = 10.11

x = 10

The value of x in the formula is 10.
