The text in the image presents two questions. Here's a breakdown and the steps for solving them:

---

### A) **Determine the density of a solution:**
The solution has a specific gravity of 1.2 at 60°F/60°F. You are asked to determine its density in:
1. Degrees Baumé (°Bé)
2. Degrees Twaddell (°Tw)
3. Kilograms per cubic meter (kg/m³)

- **Specific Gravity (SG):** Specific gravity (SG) is the ratio of the density of a solution to the density of water at a reference temperature (usually 60°F or 15.6°C).
  \[
  SG = \frac{\text{Density of solution}}{\text{Density of water}}
  \]
  
- **Conversion to Degrees Baumé (°Bé):**
  For liquids heavier than water (SG > 1), Baumé is calculated as:
  \[
  °Bé = 145 - \frac{145}{SG}
  \]
  Substituting SG = 1.2:
  \[
  °Bé = 145 - \frac{145}{1.2} = 145 - 120.83 \approx 24.17°Bé
  \]

- **Conversion to Degrees Twaddell (°Tw):**
  For liquids heavier than water, Twaddell is related to SG as:
  \[
  °Tw = (SG - 1) \times 200
  \]
  Substituting SG = 1.2:
  \[
  °Tw = (1.2 - 1) \times 200 = 0.2 \times 200 = 40°Tw
  \]

- **Density in kg/m³:**
  The density of water at 60°F is approximately 999 kg/m³. To find the density of the solution, multiply SG by this value:
  \[
  \text{Density} = SG \times \text{Density of water}
  \]
  \[
  \text{Density} = 1.2 \times 999 \, \text{kg/m}^3 = 1198.8 \, \text{kg/m}^3
  \]

### B) **Temperature conversion:**
You are asked to convert the temperature of a chemical reaction from 353.2 K (Kelvin) into:
1. Fahrenheit (°F)
2. Celsius (°C)
3. Rankine (°R)

- **Kelvin to Celsius:**
  \[
  T(°C) = T(K) - 273.15
  \]
  Substituting \( T(K) = 353.2 \):
  \[
  T(°C) = 353.2 - 273.15 = 80.05°C
  \]

- **Celsius to Fahrenheit:**
  \[
  T(°F) = T(°C) \times \frac{9}{5} + 32
  \]
  Substituting \( T(°C) = 80.05 \):
  \[
  T(°F) = 80.05 \times \frac{9}{5} + 32 = 176.09°F
  \]

- **Kelvin to Rankine:**
  \[
  T(°R) = T(K) \times \frac{9}{5}
  \]
  Substituting \( T(K) = 353.2 \):
  \[
  T(°R) = 353.2 \times \frac{9}{5} = 635.76°R
  \]
