Frequently asked questions
Is Percent Yield Calculator free to use?
Yes. Percent Yield Calculator runs entirely in your browser. There is no account, no upload, and no cost.
Does Percent Yield Calculator work on mobile?
Yes. The layout is responsive, so Percent Yield Calculator works on any phone, tablet, or desktop with a modern browser.
Can percent yield exceed 100?
In real experiments it can, often from impurities or measurement error, but the math simply divides actual by theoretical.
Why must theoretical be positive?
Theoretical yield is a maximum, so zero or negative makes the ratio meaningless and the tool rejects it.
