         P • V = n • R • T

R = 8.3143 J/(moleºK)

T = 27 + 273.16 = 300.16 ºK

molecular weight of CO2 = 44.0095 g/mol

n = (2.2 g) ⁄ (44.0095 g/mol) = 0.0499892 moles

P = (570 mm Hg) • [  (101325 Pa) ⁄ (760 mm Hg)  ]  =  75994 Pa

           P • V = n • R • T

  (75994) • V = (0.0499892) • (8.3143) • (300.16)

                V = 0.00164 m³

                V = 16.4 cm³
