The image shows a problem related to the *Conservation of Mass*, involving an escape room activity. The key elements of the activity are as follows:

- **Reactants**:
  - Steel Wool (6 grams)
  - Oxygen (1 gram)
  
- **Product**:
  - Iron Oxide (7 grams)

The problem asks: *Which equation below demonstrates that the mass was conserved?*

### Mass Conservation
The law of conservation of mass states that in a chemical reaction, the total mass of the reactants equals the total mass of the products. For this case:
\[
\text{Mass of Steel Wool (6g)} + \text{Mass of Oxygen (1g)} = \text{Mass of Iron Oxide (7g)}
\]

### Options Analysis
Let's evaluate the equations:
- **Option A: Sw6 + O1 = IrOx7**  
  This seems to represent the masses correctly (6g + 1g = 7g), which matches the conservation law.
  
- **Option B: 6g + 1g = 7g**  
  This is a straightforward statement of mass conservation, confirming the balance of mass.
  
- **Option C: SW - O = FeO**  
  This doesn't correctly describe the relationship as it suggests subtracting mass rather than adding.
  
- **Option D: Fe²O³ + O = 6 grams of steel wool**  
  This is also incorrect because it implies additional oxygen without showing mass balance properly.

### Correct Answer
The correct answer is **B**, as it directly shows that the total mass is conserved: \(6g + 1g = 7g\).
