suppose that 4.67 g of a silver salt ( agx ) is dissolved in 715.0 ml of water. a current of 2.48 a , applied for 1430 s , is required to plate out all of the silver in solution. what is the mass percentage of silver in the salt?

Respuesta :

Ag^t + e^- ------> Ag

I = 2.48 A

t = 1430 s

q = It = 2.22×1180 = 3729.6

ne- = q/F = 3729.6/96485 = 0.03+

What is mass percentage ?

The mass percent is calculated by dividing the mass of the compound or solute by the mass of the element or solute. A percent is obtained by multiplying the result by 100. The mass percent formula is (mass of element in 1 mole of compound / mass of 1 mole of compound) x 100 to determine the amount of an element in a compound.
