4.64 g of Na2So4 * xH2O were heated to yield 2.84 g of Na2So4. What is the value of x?
1 Answer | add yours
here according to me x=5
seemoles of na2so4=2.84/142=0.02 moles
moles of h2o= 0.1
x= 0.1* 1/0.02 as for every one mole of na2so4 x moles of h20 are present. the above calculation in previous answer is correct bot final value of x is wrongly calculated.
