Option D: 246 KAccording the ideal gas law: ...... (1)Here, P is the pressure, V the volume, n is the number of moles, R is the Universal gas constant and T is the temperature of the gas. The value of R is .The number of moles of gas is 0.750 moles, the volume of the cylinder is 6850 mL and the pressure of the gas is 2.21 atm.The first conversion of volume from mL to LThus,6850 mL=6.850 LPutting the values in the equation (1),the Reorganization,therefore, the temperature of the gas is 246 K.
