Can you please do question number 2 th proper tempo)Experiment 8 - Prelab Assignment1. Benzene has a freezing point of 6.00 °C, a density of 0.8787 g/mL and a molal freezing pointdepression constant (Kr) of 5.12 °C kg/mol. When 0.515 g of an unknown solute was dissolved in12.3 mL of benzene, the solution that formed was found to have a freezing point of 4.10 °C. What is themolecular mass of the unknown solute?Time (s)0153045607590T (°C)12.511.19.58.27.26.56.0Time (s)1051201351501651801952.
