You must use the appropriate ideal gas constant, R for the units you're working in. All R-values are equal, just in different units. It's best to have at least two memorized, one in SI units; Pascal and one in atmospheres.
Here is a list
R = 0.0821 liter·atm/mol·K
R = 8.3145 Pa·m3 /mol·K
R = 8.2057 m3·atm/mol·K
R = 62.3637 L·Torr/mol·K or L·mmHg/mol·K
R = 8.3145 Pa·m3 /mol·K
R = 8.2057 m3·atm/mol·K
R = 62.3637 L·Torr/mol·K or L·mmHg/mol·K
Convert 7583 mL to liters and use: R = 0.0821 L·atm/mol·K
PV = nRT
(0.9803 atm)(7.583 L) = (9.55 mol)*(0.0821 L·atm/mol·K)T
(0.9803 atm)(7.583 L) / [(9.55 mol)*(0.0821 L·atm/mol·K)] = T
Units will cancel out leaving Temperature in Kelvin.
T = 9.48 K
