The crystalline salt Na2CO3.XH20 on heating loses 63% of its mass and becomes anhydrous. The formula ofthe compound is |
|
Answer» M NA 2 CO 3 =106M H 2 O =18Let the MASS of SALT is W. Then 106+18n=W⟶(1) After heating, 10037W =106⟶(2) (63% is LOST i.e, H 2 O is lost)Putting (2) in (1),⇒106+18n= 37106×100 ⇒18n=180.4⇒n=10.02≃10 |
