Molarity Calculator

Molarity (M) is a measure of the concentration of a solution, expressed as the number of moles of solute per liter of solution. The formula is:

M = moles of solute / liters of solution

pH Calculator

pH is a measure of the hydrogen ion concentration in a solution, indicating its acidity or alkalinity. The formula is:

pH = -log[H+]
