Current Efficiency Solution

Follow our step by step solution on how to calculate Current Efficiency?

FIRST Step Consider the formula

C.E = (\frac{A}{m t}) \cdot 100

Next Step Substitute values of Variables

∴

C.E = (\frac{45g}{46g}) \cdot 100

Next Step Convert Units

∴

C.E = (\frac{0.045kg}{0.046kg}) \cdot 100

Next Step Prepare to Evaluate

∴

C.E = (\frac{0.045}{0.046}) \cdot 100

Next Step Evaluate

∴

C.E = 97.8260869565217

LAST Step Rounding Answer

∴

C.E = 97.8261
