Chemistry resources for educators
Calculator inputs round-trip through the URL, which makes it easy to drop a worked example into slides, a problem set, or an LMS. Open a calculator, fill in the values you want students to see, and copy the link.
Worked examples via URL
Every calculator preserves its inputs in the query string, so a link is a problem your students can open already populated.
