### Boiling Point Elevation Calculation**Problem:**A certain liquid X has a normal boiling point of 117.50 °C and a boiling point elevation constant \( K_b = 1.51 \, °C \cdot kg \cdot mol^{-1} \). Calculate the boiling point of a solution made of 52.3 g of urea (CH\(_4\)N\(_2\)O) dissolved in 650. g of X.**Solution:**Given:- Normal boiling point of liquid X, \( T_b = 117.50 \, °C \)- Boiling point elevation constant, \( K_b = 1.51 \, °C \cdot kg \cdot mol^{-1} \)- Mass of urea, \( m_{\text{urea}} = 52.3 \, \text{g} \)- Mass of solvent (liquid X), \( m_{\text{solvent}} = 650. \, \text{g} \)The boiling point elevation (\( \Delta T_b \)) is calculated using the formula:\[ \Delta T_b = K_b \cdot m \]where \( m \) is the molality of the solution. Molality (m) is calculated as:\[ m = \frac{\text{moles of solute}}{\text{kilograms of solvent}} \]**Step 1: Calculate the moles of urea.**- Molar mass of urea (CH\(_4\)N\(_2\)O): \[ M_{\text{urea}} = 12.01 (\text{C}) + 4 \times 1.01 (\text{H}) + 2 \times 14.01 (\text{N}) + 16.00 (\text{O}) = 60.06 \, \text{g/mol} \]- Moles of urea: \[ \text{moles of urea} = \frac{52.3 \, \text{g}}{60.06 \, \text{g/mol}} = 0.8704 \, \text{mol} \]**Step 2: Calculate the molality (m).**- Mass of solvent (in kg): \[ \text{mass of solvent
