A sealed 29 m³ tank is filled with 9000 moles of ideal oxygen gas (diatomic)at an initial temperature of 270 K.The gas is heated to a final temperature of 330 K.The atomic mass of oxygen is 16.0 g/mol.The initial pressure of the gas,in MPa,is closest to:

The ideal gas law is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature. We can rearrange this equation to solve for P: P = nRT/V.Plugging in the given values, we get: P = (9000 mol)(8.31 J/mol*K)(330 K)/(29 m^3) = 8.8 MPa.Converting to MPa, we get: P = 8.8 MPa / 1000 kPa/MPa = 0.79 MPa.Therefore, the initial pressure of the gas is closest to 0.79 MPa.
