**Heating Diethyl Ether: Calculation of Heat Absorption**

**Question:**
What is the total amount of heat absorbed in kJ when 39 grams of diethyl ether at 20°C is heated to 136°C?

**Data Provided:**
- **Molar Mass:** 74 g/mol
- **Melting Point:** -116°C
- **Boiling Point:** 34.5°C
- **Heat of Fusion (H_fus):** 7,270 J/mol
- **Heat of Vaporization (H_vap):** 27,710 J/mol
- **Specific Heat (liquid, c_s(l)):** 3.74 J/g°C
- **Specific Heat (gas, c_s(g)):** 2.35 J/g°C

**Instructions:**
Show work on upload. 

This data will be used to calculate the heat absorbed during the phase transitions and temperature rise of diethyl ether using principles of thermodynamics. The process involves calculating the heat required for warming the ether to its boiling point, the phase change from liquid to gas, and finally, heating the vapor to the final temperature.
