**Question 12 of 14**

*How many moles of propylene (C₃H₆) are in 25.0 g of the substance?*

Below the question, there is an interactive tool where users can input calculations. The interface includes:
- A multiplication factor input labeled "ADD FACTOR": `x (), () = ____`
- A section labeled "ANSWER" where the result is displayed.
- A "RESET" button to clear inputs and start over.

Underneath these input fields are a series of selectable numerical values for calculations:
- Atomic and molecular values: `1.01`, `4.15 × 10⁻²³`, `12.01`, `36.03`
- Values relevant to calculations: `25.0` (mass of substance), `6.022 × 10²³` (Avogadro’s number), `42.09` (likely molar mass of C₃H₆), among others.
- Additional numbers: `0.694`, `0.594`

At the bottom, there are red buttons likely related to unit conversions or specific actions: "molecules C H", "mol C H", "g C H", "g C H/mol", "mol C H".

This setup allows for the calculation of moles given a mass using stoichiometric principles. Users are meant to select appropriate values to solve for the number of moles of propylene in the given mass.
