The number of intensive properties among the following is
Density, temperature, volume, pressure, enthalpy, entropy, viscosity, force, molar heat capacity, free energy, heat capacity.

Explanation

To determine the number of intensive properties among the given list, we need to classify each property as either intensive or extensive.

### Step-by-Step Solution:

1. **Understanding Intensive and Extensive Properties**:
- **Intensive Properties**: These properties do not depend on the amount of substance present. They are characteristic of the material itself. Examples include density, temperature, pressure, viscosity, and molar heat capacity.
- **Extensive Properties**: These properties depend on the amount of substance present. Examples include volume, enthalpy, entropy, force, heat capacity, and free energy.

2. **List of Given Properties**:
- Density
- Temperature
- Volume
- Pressure
- Enthalpy
- Entropy
- Viscosity
- Force
- Molar Heat Capacity
- Free Energy
- Heat Capacity

3. **Classifying Each Property**:
- **Density**: Intensive (depends on the nature of the material)
- **Temperature**: Intensive (does not depend on the amount)
- **Volume**: Extensive (depends on the amount)
- **Pressure**: Intensive (does not depend on the amount)
- **Enthalpy**: Extensive (depends on the amount)
- **Entropy**: Extensive (depends on the amount)
- **Viscosity**: Intensive (depends on the nature of the material)
- **Force**: Extensive (depends on the amount)
- **Molar Heat Capacity**: Intensive (per mole, does not depend on the amount)
- **Free Energy**: Extensive (depends on the amount)
- **Heat Capacity**: Extensive (depends on the amount)

4. **Counting Intensive Properties**:
- The intensive properties identified are:
- Density
- Temperature
- Pressure
- Viscosity
- Molar Heat Capacity
- Total Intensive Properties = 5

### Final Answer:
The number of intensive properties among the given list is **5**.
