LD50 ('50%-Lethality' dose) is a meaured value from many statical investigations. So there's only a good definition on how it should be 'measured' and can not be calculated from other values by formula.
An LD50 is a standard measurement of acute toxicity that is stated in milligrams (mg) of pesticide per kilogram (kg) of body weight.
Formeldehyde is a substance used to preserve dead bodies.
In toxicology, the median lethal dose, of a toxin is the dose required to kill half the members of a tested population after a specified test duration. LD50 figures are frequently used as a general indicator of a substance's acute toxicity.
The substance with the chemical formula CH3COONa H2O is sodium acetate monohydrate, which is a hydrated form of sodium acetate. It is commonly used as a buffering agent and in the production of pharmaceuticals and food additives.
The calculation fraction of enzyme bound to substrate is used when determining the Michaelisâ??Menten equation. It is widely used in the enzyme kinetics.
Equivalent weight = Molar mass of a substance/electrical charge of the ions (positive or negative) formed in solution Also the equivalent weight of a substance react with 1 mole of hydrogen. Today this expression is rarely used.
A formula.
This formula is used in the calculation for density, Density=mass/volume,normally in the calculation of liquid volume or density.

SUM is a function. It can be used as part of a formula which can carry out a calculation.

There are several formulae named after Gauss; anyway, a formula normally doesn't have a single answer, rather, the answer depends on the specific numbers used for the calculation.
LD50 is Representative as lethal dose 50% when your talking about how much it will take the measurement in in g, some times in mL but mostly g (grams).
Refined substance can be a pure substance depending on the type of sugar used. If the refined sugar is white, then it is a pure substance. If it the refined sugar is brown, then it is not a pure substance.
The basic formula used to calculate catalase levels is (units/mg protein/min). Results differ according to provided information, and organisms in which it is present.
