plz be clear about the answers
Pls ans both 1) A mixture of gases at 30.0°C contains 0.850 moles of oxygen, 0.850 moles of argon and 12.5 moles of nitrogen. The mixture has a volume of 15.0 L. Calculate the mole fractions and the partial pressures of the gases in the mixture. After calculating the mole fractions, write the answer in the correct number of significant figures. When calculating the partial pressures, use all the digits you calculated in the mole fraction and then write the answer in the correct number of significant figures. 2)Calculate the pressure exerted by 4.37 moles of chlorine with a volume of 2.45 L at a temperature of 38.0°C using van der waal’s law. Also calculate the pressure using the ideal gas law. Do not round-up till the end and show all of your units and how they cancel.
