For Serious Students
Molecular calculators, equation balancers, pH tools and more, built by an expert, completely free. No signup. No limits.
Most Used Chemistry Tools
Fast, precise calculators for the problems students repeat every week.
Molecular Weight Calculator
Calculate molar mass from formulas with parentheses and bracket groups.
M = Σ(atomic mass × count)
Chemical Equation Balancer
Balance chemical equations and verify atom counts on both sides.
reactant atoms = product atoms
pH Calculator
Calculate pH, pOH, [H+], and [OH-] for acid-base problems.
pH = -log[H+]
Molarity Calculator
Solve concentration, moles, and volume with M = n/V.
M = n / V

Yes. The calculators, references, and notes are free for educational use, with monetization planned through ads, premium resources, tutoring, and affiliate resources.
The site is designed around standard chemistry workflows, textbook formulas, and student-friendly explanations across chemistry topics.
The lower-right chemistry chat uses a secure server route so questions can be answered with site context without exposing API keys in the browser.
Yes. The interface is responsive, with mobile navigation, single-column tools, and smaller ad placements.
No calculator input is stored by default. The chemistry chat sends a question to the server only when you explicitly ask it.
