Chem Calc is a versatile chemistry calculator designed to help students, educators, and professionals perform a wide range of calculations quickly and accurately. Whether you need to look up element data, balance a chemical equation, calculate molar mass, determine solution pH, or explore gas‐law relationships, Chem Calc puts essential tools at your fingertips. Internet access is required only for reaction lookups—most calculations work offline.

Key Features

Interactive Periodic Table
Browse all known chemical elements with up-to-date atomic weights, electron configurations, electronegativity values, and isotope distributions. Tap any element to view detailed properties such as atomic radius, oxidation states, and standard conditions.

Reaction Search & Equation Balancer
Search a built-in database of common inorganic and organic reactions by reactant or product names. Once you select a reaction, Chem Calc balances it automatically and calculates stoichiometric coefficients.

Molar Mass & Formula Weight Calculator
Enter any valid chemical formula (e.g., C₆H₁₂O₆, Fe₂O₃, KMnO₄) and get the precise molar mass. Chem Calc supports nested parentheses, hydrates, and fractional subscripts.

pH & Acid–Base Calculations
Compute pH, [H⁺], and [OH⁻] for strong acids/bases or weak acids/bases with known pKa/pKb values.

Gas Laws & Ideal Gas Calculator
Solve PV = nRT problems by entering any two of P (pressure), V (volume), n (moles), T (temperature), or R (gas constant). Convert between units (atm, mmHg, Pa, L, mL, K, °C) with a single tap.

Concentration & Dilution Tools
Calculate molarity (M), molality (m), normality (N), mass percent, and volume percent. Perform dilution calculations to find final concentration or volume needed.

History & Favorites
All recent calculations are saved in a history list so you can revisit them later.

Unit Converter
Quickly convert between grams, moles, liters, particles (Avogadro’s number), and concentration units. Drop-down menus make it easy to switch units without retyping.

Why Chem Calc?

Accurate & Reliable: Constantly updated atomic weights, reaction data, and dissociation constants ensure your calculations match textbook or laboratory standards.

Intuitive Design: Clean interface minimizes the number of taps needed. Input fields accept chemical notation (subscripts, superscripts) and common abbreviations (e.g., “H2SO4” or “Fe(NO3)3·9H2O”).

Offline Functionality: Most features work even without a network connection. Only reaction lookups require Internet.

Perfect for Learning & Lab Work: From checking homework answers to supporting real-world experiments, Chem Calc covers a broad range of use cases: high school chemistry, university labs, environmental testing, and industrial quality control.

Regular Updates: Our team actively adds new reactions, updates element data, and refines calculators based on user feedback.

Download Chem Calc today and streamline every aspect of your chemistry work—no more flipping through tables, scribbling on paper, or searching the web for constants. With Chem Calc, all essential chemistry tools are in one convenient app.
