Calculators

Calculates the molarity of a solution given the number of moles of solute and the volume of the solution in liters. Also calculates mass from molarity, volume and molecular weight.

Converts percentage concentration of a solution to molarity, given the density and molecular weight of the solute.

Calculates the molecular weight (also known as molar mass) of a chemical compound based on the sum of the atomic weights of each element in the molecular formula.

Calculates the pKa value of a solution using either the Henderson-Hasselbalch equation or the acid dissociation constant (Ka).

Calculates the rate constant (k), reaction rate, or substance concentration using the rate law equation.

Calculates the type of chemical bond formed between two atoms based on the difference in their electronegativity values.

Calculates the effective nuclear charge (Zeff) experienced by an electron in an atom, taking into account the shielding effect of other electrons.

Calculates the osmolarity of a solution based on the molar concentration of solutes.

Calculates the relationship between pressure, volume, and temperature of a gas using the combined gas law: (P1 * V1) / T1 = (P2 * V2) / T2. This calculator allows you to solve for any one of these variables, given the others.

Calculates pressure, volume, temperature, or the number of moles of an ideal gas using the Ideal Gas Law: PV = nRT. Where P = pressure, V = volume, n = number of moles, R = ideal gas constant, and T = temperature.
