Please state the correct answer with solution, thank u so much, this means a lot. thank u for helping

46-50.) The temperature of a sample of an ideal gas in a sealed container is raised from 27 C to 91 F. If the initial pressure of the gas was 3.0 atm, at constant volume, what is the final pressure? a. 3.06 aten b. 10.11 atm c. 2.03 atm d. 9.8 atm SCAN COMPUTATION (46-50) 51-55.) A 5.0 L sample of gas is collected at 400. mmHg at 727C. What is the volume if the temperature were cooled to 77C and the pressure increased to 700 mmHg? a. 2.50 L o b. 50L C. 250 mL o d. 1.0L SCAN COMPUTATION (51-55) 56-60.) The pressure of 4.0 L of an ideal gas in a flexible container is decreased to one-third of its original pressure and its absolute temperature is decreased by one-half. The volume then is? a. 1.0L b. 6.0L c. 4.0 mL o d. 8,0 SCAN COMPUTATION (56-60) 61-65.) An ideal gas contained in 5.0 L chamber at a temperature of 37C. If the gas exerts a pressure of 2.0 atm on the walls of the chamber, which of the following expressions is equal to the number of moles of the gas? * a 1.0 mol OO b. 0.038 mol c. 0.04 mol d. 0.39 mol SCAN COMPUTATION (61-65) - 66-70.) A sample of 0.010 mole of nitrogen dioxide gas is confined at 127C and 2.5 atmospheres. What would be the pressure of this sample at 27C and the same volume? * a. 0.033 atm b. 1.25 atm c. 1.88 atm d. 0.53 atm c SCAN COMPUTATION (66-70) * 71-75.) Determine the Celsius temperature of2.49 moles of gas contained 5 in a 1.00 L container at a pressure of 143kPa.* O a. 266 C O b.-266C O c. 266.09 C O d.-266.09 C SCAN COMPUTATION (71-75) *
