### Determining the Quantity of Atoms in a Given Mass of Vanadium

**Objective:**
To determine the quantity of atoms of vanadium in a specified mass (1.28 grams) of vanadium.

**Equation Setup:**
A visual representation of the problem depicts a formula box to calculate the number of atoms. The formula includes a multiplication and division format with input boxes for numerical values.

**Tools Available:**
1. **Numeric Inputs:**
   - 1.28 (grams of vanadium)
   - Other constants and conversion factors such as Avogadro's number, \(6.022 \times 10^{23}\)

2. **Operations:**
   - Multiplication (×)
   - Parentheses for grouping calculations

3. **Factor Units:**
   - g V/mol (grams per mole of vanadium)
   - g V (grams of vanadium)
   - atoms V (atoms of vanadium)
   - mol V (moles of vanadium)
   - kg V (kilograms of vanadium)

**Steps for Calculation:**
1. Start with the given mass of vanadium (1.28 grams).
2. Use Avogadro's number to convert from moles to atoms.
3. Apply the correct conversion factors to solve for the number of atoms.

**Buttons:**
- **Add Factor:** Includes operations and constants in the calculation.
- **Delete:** Removes input factors.
- **Answer:** Provides the calculated result.
- **Reset:** Clears all inputs to start over.

**Visual Diagram:**
The interface includes sections for starting amounts, multiplication setups for conversion, and selection of numeric values and units. There's an intuitive layout for adding and managing conversion factors.

This educational setup allows users to practice calculating the number of atoms in a given mass, simulating a hands-on approach to understanding chemical calculations and conversions in real-time.
