Question
**Calculating Molality and Molarity**

A student dissolves 13.8 g of glucose (C₆H₁₂O₆) in 125 mL of a solvent with a density of 1.15 g/mL. The student notices that the volume of the solvent does not change when the glucose dissolves in it. Calculate the molarity and molality of the student's solution. Round both of your answers to 2 significant digits.

- **Molarity** (M):
  \[
  \text{Enter molarity here}
  \]

- **Molality** (m):
  \[
  \text{Enter molality here}
  \]

Use the buttons to check your answers. 

**Graph/Diagram Description:**

There is an interactive section with input fields labeled "molality" and "molarity" for user input. Below this, there are expandable window options, likely for resizing or full-screen viewing of content. 

**Note:** Students can click “Check” to validate their answers after input. The layout includes standard web navigation elements and a link to additional explanations if needed.
