![**Title: Calculating the Molality of Sugar in Spinal Fluid**
**Introduction:**
Understanding the concentration of substances within bodily fluids is crucial in various medical and scientific fields. This guide will focus on calculating the molality of a sugar, specifically glucose (C₆H₁₂O₆), in a sample of normal spinal fluid.
**Problem Statement:**
Calculate the molality of a sugar in a sample of normal spinal fluid. The concentration of this sugar, C₆H₁₂O₆, is around 76 µg per 100 mg of fluid.
**Explanation:**
1. **Concentration Given:**
- Sugar: C₆H₁₂O₆ (Glucose)
- Concentration: 76 µg per 100 mg of fluid
2. **Definitions:**
- *Molality (m)* is defined as the number of moles of solute per kilogram of solvent.
- It is calculated using the formula:
\[ m = \frac{\text{moles of solute}}{\text{kilograms of solvent}} \]
3. **Steps to Calculate Molality:**
- Convert the mass of glucose from micrograms to grams for easier calculations.
- Calculate the number of moles of glucose using its molar mass.
- Convert the mass of the fluid to kilograms.
- Apply the molality formula to find the result.
By conducting these calculations, you'll gain insights into the precise concentration of glucose within the spinal fluid, a critical factor for various medical analyses.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa96b4bb0-d0b0-42c4-bbdb-20cfc9de1635%2Fc0098525-d612-4ab8-9d14-f9bc770acd07%2Fjnp5a9x.jpeg&w=3840&q=75)
