Active Mass Solution

STEP 0: Pre-Calculation Summary

Formula Used

Active mass = Weight of Solute/Molecular Weight
M = w/MW
This formula uses 3 Variables

Variables Used

Active mass - (Measured in Mole per Cubic Meter) - Active mass gives the relation between rate of chemical reaction and concentrations of reactants.
Weight of Solute - (Measured in Kilogram) - The Weight of Solute is the quantity or amount of solute present in the solution.
Molecular Weight - (Measured in Kilogram) - Molecular Weight is the mass of a given molecule.

STEP 1: Convert Input(s) to Base Unit

Weight of Solute: 21 Gram --> 0.021 Kilogram (Check conversion here)
Molecular Weight: 120 Gram --> 0.12 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M = w/MW --> 0.021/0.12

Evaluating ... ...

M = 0.175

STEP 3: Convert Result to Output's Unit

0.175 Mole per Cubic Meter -->0.000175 Mole per Liter (Check conversion here)

FINAL ANSWER

0.000175 Mole per Liter <-- Active mass

(Calculation completed in 00.004 seconds)

Equilibrium Constant for Reverse Reaction

Go Reverse Equilibrium Constant = ((Equilibrium Concentration of A^Number of Moles of A)*(Equilibrium Concentration of B^No. of Moles of B))/((Equilibrium Concentration of C^No. of Moles of C)*(Equilibrium Concentration of D^No. of Moles of D))

Equilibrium Constant for Reaction when Multiplied with Integer

Go Equilibrium Constant Multiplied = (Equilibrium Constant^Number)

Weight of Reactant given Active Mass

Go Weight of Solute = Active mass*Molecular Weight

Active Mass

Go Active mass = Weight of Solute/Molecular Weight

Active Mass Formula

Active mass = Weight of Solute/Molecular Weight
M = w/MW

What is law of mass action?

This law states that 'The rate of a chemical reaction at a given temperature is directly proportional to the product of the active mass or molar concentration of the reactants at that instant'.
This law is applicable to all reactions occurring in the gas phase or in the liquid phase.

How to Calculate Active Mass?

Active Mass calculator uses Active mass = Weight of Solute/Molecular Weight to calculate the Active mass, The Active mass formula is defined as the concentration of a reacting substance expressed usually in moles per liter. Active mass is denoted by M symbol.
