Parse chemical formulae and hydrates, inspect element contributions and calculate with cited CIAAW atomic weights.
Useful to know
Can this answer every science question?
No. Each model has stated limits. Use structured fields when a prose question is unsupported. It does not predict reaction products or provide experiment procedures.
Are these official curriculum mappings?
No. These are concept-based resources. KICD and legacy KCSE mappings remain under review; no endorsement is claimed.
Where are my inputs stored?
Questions and scores remain in this tab only and are cleared by reset or reload. Copy and print are optional actions you control.

Science learning notes
Build molar mass from the formula
Count each element, including atoms inside repeated groups and hydrates. Multiply counts by the cited abridged atomic weights and add the contributions. Molar mass is mass per mole; its classroom unit here is g mol⁻¹.
Example: Ca(OH)2
Common mistake: The outside 2 in Ca(OH)₂ repeats both O and H; it does not repeat Ca.
Why are molar masses approximate?
Normal isotopic composition varies and source weights have uncertainty. The output cites classroom approximations and a conservative uncertainty sum.
