Solution Chemistry

• Molarity Calculator — Calculate the molar concentration of a solution from solute mass, molar mass, and solution volume. Essential for preparing standard solutions and serial dilutions in the laboratory.
• pH Calculator — Determine pH, pOH, and the acidity or alkalinity of a solution from hydrogen ion concentration [H⁺], hydroxide ion concentration [OH⁻], or direct pOH input. Useful for acid-base equilibrium and buffer calculations.

Stoichiometry & Mass Calculations

• Molar Mass Calculator — Compute moles, mass, or molar mass using the fundamental relation n = m / M. Indispensable for stoichiometric calculations and accurate reagent preparation.
• Percent Yield Calculator — Evaluate the efficiency of a chemical reaction by calculating percent yield from actual and theoretical yield values. Widely used in synthetic and analytical chemistry.

Physical Chemistry

• Density Calculator — Compute density, mass, or volume using ρ = m/V with support for multiple unit systems. Applicable in material science, fluid mechanics, and physical chemistry experiments.

Reference Databases

• NIST Chemistry WebBook — Authoritative thermochemical, thermophysical, and spectroscopic data for a large number of chemical compounds, maintained by the National Institute of Standards and Technology (USA). Widely used in research for obtaining standard property values.
• Wolfram Alpha — Chemistry — Computational knowledge engine covering chemical formulas, reaction balancing, thermodynamic properties, and molecular structure data. Useful for verifying calculations and exploring chemical properties interactively.
