Answer :
At a current of 5.80 A, 24.5 g of aluminum may be plated onto the item in 755 minutes.
Electric current is the quantity of electric charge moving across a given area at a certain rate. I designates it. Ampere is the SI unit for current. It is measured with an instrument called an ammeter. The presence of charge carriers results in the charge. Charge carriers often include electrons or entities deficient in electrons. A key characteristic of subatomic particles is charge. Coulomb is the common unit of charge.
The following is an expression for the relationship between the charge and the electric current:
Q = It …… (1)
Quantity Q in this case refers to a substance's charge.
Electric current I is.
The amount of time, t, that the charge spends traveling through the substance
The time must first be converted to seconds. For this, the conversion factor is 1 minute = 60 seconds.
Time can therefore be calculated as follows:
(60 sec / 1 min) / t = 755 min = 45300 sec
I has a value of 5.80 A.
T is 45300 seconds in length.
Replace these numbers in the equation (1).
262740 C is equal to Q = 5.80 A (45300 sec).
The following equation can be used to determine the equivalent weight of aluminum:
Weight is calculated as molecular weight of aluminum divided by its valency. Change 3 for the valency of Al and 26.98 g for the molecular weight of Al in the equation (2).
Eq. weight = 26.98/ 3 = 8.99 g mass of Al deposited = (Eq. weight Q)/ F = 8.99 262740 / 96485 = 24.5 g
