E Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

E Factor = Total Mass of Waste/Mass of Product
EF = MW/MPr
This formula uses 3 Variables

Variables Used

E Factor - The E factor is the actual amount of waste produced in the process and takes waste from all auxiliary components.
Total Mass of Waste - (Measured in Kilogram) - Total Mass of Waste is the weight of waste generated in reaction.
Mass of Product - (Measured in Kilogram) - Mass of Product can be calculated using the balanced equation, the mass and relative formula mass of the limiting reactant, and the relative formula mass of the product.

STEP 1: Convert Input(s) to Base Unit

Total Mass of Waste: 5 Kilogram --> 5 Kilogram No Conversion Required
Mass of Product: 17 Kilogram --> 17 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

EF = MW/MPr --> 5/17

Evaluating ... ...

EF = 0.294117647058824

STEP 3: Convert Result to Output's Unit

0.294117647058824 --> No Conversion Required

FINAL ANSWER

0.294117647058824 ≈ 0.294118 <-- E Factor

What are green chemistry metrics?

Green chemistry metrics describe aspects of a chemical process relating to the principles of green chemistry. The metrics serve to quantify the efficiency or environmental performance of chemical processes, and allow changes in performance to be measured. The motivation for using metrics is the expectation that quantifying technical and environmental improvements can make the benefits of new technologies more tangible, perceptible, or understandable.

How to Calculate E Factor?

E Factor calculator uses E Factor = Total Mass of Waste/Mass of Product to calculate the E Factor, The E Factor formula is defined as the ratio of the mass of waste per mass of product. It highlights the waste produced in the process as opposed to the reaction, thus helping those who try to fulfil one of the twelve principles of green chemistry to avoid waste production. E Factor is denoted by EF symbol.

How to calculate E Factor using this online calculator? To use this online calculator for E Factor, enter Total Mass of Waste (MW) & Mass of Product (MPr) and hit the calculate button. Here is how the E Factor calculation can be explained with given input values -> 0.294118 = 5/17.

FAQ

What is E Factor?

The E Factor formula is defined as the ratio of the mass of waste per mass of product. It highlights the waste produced in the process as opposed to the reaction, thus helping those who try to fulfil one of the twelve principles of green chemistry to avoid waste production and is represented as EF = MW/MPr or E Factor = Total Mass of Waste/Mass of Product. Total Mass of Waste is the weight of waste generated in reaction & Mass of Product can be calculated using the balanced equation, the mass and relative formula mass of the limiting reactant, and the relative formula mass of the product.

How to calculate E Factor?

The E Factor formula is defined as the ratio of the mass of waste per mass of product. It highlights the waste produced in the process as opposed to the reaction, thus helping those who try to fulfil one of the twelve principles of green chemistry to avoid waste production is calculated using E Factor = Total Mass of Waste/Mass of Product. To calculate E Factor, you need Total Mass of Waste (MW) & Mass of Product (MPr). With our tool, you need to enter the respective value for Total Mass of Waste & Mass of Product and hit the calculate button.
