Calculators

Calculates the required amount of each substance in a mixture based on a given mixing ratio and total desired amount.

Calculates the molar mass of a gas using the ideal gas law (PV = nRT), where molar mass (M) = mass / moles. This calculator rearranges the ideal gas law to solve for molar mass: M = (mass * R * temperature) / (pressure * volume).

Calculates the normality of a solution, which represents the number of equivalents of solute per liter of solution.

Converts between moles, mass, and molecular weight.

Calculates the volume of stock solution needed to create a diluted solution of a desired concentration and volume using the formula C1V1 = C2V2.

This calculator helps you convert between different concentration units, including molarity (mol/L) and percentage concentration (% w/v, % v/v, % w/w).

Calculates the amount of bleach and water needed to achieve a desired chlorine concentration for disinfection purposes.

Calculates the pH, pKa, or the ratio of acid and conjugate base concentrations using the Henderson-Hasselbalch equation. This equation is commonly used in chemistry, biology, and medicine to estimate the pH of a buffer solution.

This calculator helps determine the name of an ionic compound based on the cation and anion provided.

Calculates the average atomic mass of an element based on the masses and natural abundances of its isotopes.
