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

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
