I need to answer both questions please

Question 3 1.29 pts Using the Virial equation of state, determine the pressure of 3.17 moles of a gas in box with volume 8 L at temperature of 5.2 C. Assume B = -0.042 L mold and that all other coefficients are zero. Express your answer to 1 decimal place in kPa (XXXX.X). Question 4 1.29 pts Pretend that there are three gases in a box. The number of moles of each gas are: Gas 1: 1 Gas 2: 1.8 . Gas 3: 0.2 Determine the mole fraction of Gas 2 in the mixture. Express your answer to three decimal places (X.XXX)
