Contact ChemSolver
Does a calculation look wrong? Found a content correction or accessibility problem? Send a clear example and we will use it to improve the chemistry tools.
Email support
Email is the best way to report a problem because chemistry issues usually need the exact formula, equation, or page URL.
Send messages to
support@chemsolver.orgWe read support messages about calculation errors, formulas that do not work as expected, rounding questions, page corrections, and broken links. Please do not send private student records, answer keys you do not have permission to share, or sensitive personal information.
What to include
A precise report makes it much easier to check what happened.
Exact input
Copy the formula, equation, mass, unit, charge, or question exactly as you entered it.
Page URL
Include the calculator or answer-page link, especially if the problem was already filled in when the page opened.
Expected result
Tell us what your textbook, instructor, or manual answer says and which rounding rule it uses.
Context
Mention whether the issue is a calculation error, wording correction, accessibility problem, or new calculator suggestion.
What we can help with
The support address is for website questions and chemistry calculator corrections, not for urgent lab or safety decisions.
Good support requests include a balanced equation that appears wrong, a molar mass total that differs from your classroom rounding, a Lewis structure input that gives a confusing message, a typo on an answer page, or a calculator result that needs a clearer step-by-step explanation.
We cannot complete graded assignments for you, provide emergency chemical safety guidance, or certify results for laboratory, industrial, regulatory, or medical use. For those situations, use your instructor, supervisor, safety data sheets, or a qualified professional.
Useful pages before you email
Some questions can be answered faster by trying a focused calculator or checking a related answer page.
