Water Soluble Extractive Value Solution

STEP 0: Pre-Calculation Summary

Formula Used

Water Soluble Extractive Value = (Dish Residue Weight-Dish Weight)*4*100/Sample Weight
EV = (B-A)*4*100/W
This formula uses 4 Variables

Variables Used

Water Soluble Extractive Value - Water Soluble Extractive Value indicates the nature of chemical constituents present in drugs.
Dish Residue Weight - (Measured in Kilogram) - Dish Residue Weight is combined weight of dish and residue.
Dish Weight - (Measured in Kilogram) - Dish Weight is empty weight of dish.
Sample Weight - (Measured in Kilogram) - Sample Weight is weight of plant material taken.

STEP 1: Convert Input(s) to Base Unit

Dish Residue Weight: 30 Gram --> 0.03 Kilogram (Check conversion here)
Dish Weight: 20 Gram --> 0.02 Kilogram (Check conversion here)
Sample Weight: 150 Gram --> 0.15 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

EV = (B-A)*4*100/W --> (0.03-0.02)*4*100/0.15

Evaluating ... ...

EV = 26.6666666666667

STEP 3: Convert Result to Output's Unit

26.6666666666667 --> No Conversion Required

FINAL ANSWER

26.6666666666667 ≈ 26.66667 <-- Water Soluble Extractive Value

Percent Post Implantation Loss

Go Percent Postimplantation Loss = ((Number of implants-Number of litters)/Number of implants)*100

Percent Preimplantation Loss

Go Percent Preimplantation Loss = ((Number of CL-Number of implants)/Number of CL)*100

Post Implantation Loss

Go Preimplantation Loss = Number of implants-Number of litters

Preimplantation loss

Go Preimplantation Loss = Number of CL-Number of implants

Water Soluble Extractive Value Formula

Water Soluble Extractive Value = (Dish Residue Weight-Dish Weight)*4*100/Sample Weight
EV = (B-A)*4*100/W

What is extractive value?

All the chemical constituents are soluble either in polar, semi polar or organic solvents. Total soluble constituents of the drug in any particular solvent or mixture of solvents may be called its extractive value or percent extractive.
