Explanation / Answer

Mass = 0.290g

Molar mass of CO2 = 44.01g/mol

Moles of CO2 = mass/molar mass = 0.290g/44.01g/mol

Moles, n = 0.00659

Volume,V = 560mL = 0.560L

Pressure,P = 436mmHg

760mmHg = 1atm

436mmhg = 436/760atm = 0.574atm

R = 0.0821Latm/molK

PV = nRT

T = PV/nR

T = 0.574atm*0.560L /0.00659mol*0.0821latm/molK

T = 594.1K

2. T = 594.1K

T in celsius = 594.1-273.1 = 321
