Calculate the exact amount of total electrical charge (in Coulombs) that is successfully consumed wh — Electrochemistry Chemistry Question

💡 Solution & Explanation

The total quantity of charge ($Q$) is the product of steady current ($I$) and total time ($t$) in seconds. $I = 100\text{ mA} = 0.1\text{ A}$. The time $t = 30\text{ minutes} = 30 \times 60\text{ s} = 1800\text{ seconds}$. Using the formula $Q = I \times t$, $Q = 0.1\text{ A} \times 1800\text{ s} = 180\text{ Coulombs}$.
