Distinguish between electrochemical equivalent and chemical equivalent

Chemical equivalent of an element is the value obtained by dividing the atomic weight of the given element by its valency. Electrochemical equivalent: Electrochemical equivalent on the other hand, refers to the mass of substance deposited when a current of 1 Ampere is passed for 1 Second during electrolysis. thats the answer when i first saw this i thought it was just one of thos free points with gibberish XD

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
