Mini Tools Collection
ToolPatch is a growing collection of focused utilities. Each page handles one task with clear inputs, fast results, and practical outputs.
Solve pressure, volume, moles, or temperature with PV=nRT.
Use the ideal gas law to solve one missing variable given the other three. Great for gas-law homework, exam prep, and quick unit-aware checks.
Solve molarity, moles, or volume using M = n/V.
Calculate solution concentration and dilution prep values from moles and volume. Useful for lab prep, chemistry coursework, and quick concentration checks.
Convert hydrogen ion concentration to pH and classify acidity/basicity.
Compute pH and pOH from [H+] or derive [H+] from pH quickly. Useful for acid-base questions, buffer prep, and classroom exercises.
Use C1V1=C2V2 to solve dilution and solution prep problems.
Determine unknown concentration or volume for dilution planning with one equation. Great for lab workflows, stock solution prep, and chemistry practice.
Calculate percent yield and loss from theoretical and actual yield values.
Enter theoretical and actual yield to evaluate reaction efficiency. Helpful for lab reports, stoichiometry checks, and process optimization basics.
