STEM REASONING AND EVIDENCE WORKBENCH
Convert between moles and representative particles with a supplied Avogadro constant and claim-error evidence.
Review output
Load the worked example to inspect realistic inputs, or enter anonymous classroom or laboratory evidence. Results remain in this browser tab until you copy or download them.
Transparent method
Particles equal moles multiplied by the supplied Avogadro constant. Moles equal particles divided by that constant. The workbench calculates with the full entered values, compares the learner claim by relative error, and uses a 0.01 percent review threshold before formatting very large or small numbers in scientific notation. A supported row demonstrates a correct direct conversion for the entered entity and constant. It does not show whether the learner selected the appropriate entity or can connect a chemical formula with constituent particles. Ask for a dimensional-analysis setup with units that cancel and an order-of-magnitude estimate.
Confirm the question, approved source, units, notation, signs, response coding, model assumptions, and review threshold. Keep an unchanged copy of measurements or learner evidence.
Run the worked example, inspect every intermediate row, and compare the result with a hand calculation, diagram, representation, periodic table, or approved laboratory method.
Record the method, assumptions, uncertainty, units, classifications, and flagged rows. Verify the editable report independently before instruction, assessment, or laboratory use.
How to interpret the result
Use for direct amount-of-substance conversions after learners identify the representative entity. It does not infer the entity from a formula, count atoms inside molecules, use molar mass, solve reaction stoichiometry, convert sample mass, account for purity, or decide significant figures from an experimental context.
One mole maps to the supplied 6.02214076 times ten to the twenty-third entities. A quarter mole gives one quarter of that count, and half that particle count converts back to 0.5 mol. The final two-mole claim uses the wrong exponent and is flagged by a large relative error.
Particles equal moles multiplied by the supplied Avogadro constant. Moles equal particles divided by that constant. The workbench calculates with the full entered values, compares the learner claim by relative error, and uses a 0.01 percent review threshold before formatting very large or small numbers in scientific notation.
A supported row demonstrates a correct direct conversion for the entered entity and constant. It does not show whether the learner selected the appropriate entity or can connect a chemical formula with constituent particles. Ask for a dimensional-analysis setup with units that cancel and an order-of-magnitude estimate.
Do not invert the conversion factor, lose an exponent, treat atoms and molecules as interchangeable, multiply by subscripts without stating the requested entity, or round the constant before calculation. Write units beside every factor, check whether the result should be extremely large, and report defensible significant figures.
Learning boundary
This browser-local workbench applies only the disclosed rules. It cannot diagnose a learner, certify an experiment, establish a chemical structure, or replace teacher, laboratory, and safety judgment.

Practical questions
No. Processing occurs in the current browser tab. Avoid personal information and retain authoritative records only in the school-approved system.
No. It describes entered evidence under one disclosed rule. Compare several evidence sources and ask for reasoning before drawing a conclusion.
Treat it as an editable calculation aid. Show your own reasoning, cite required sources, and follow the course method and academic-integrity rules.
