How many moles of oxgen are produced for a volume change of 33.19 ml at 23.43 C and 30.41 inHg?

Solutions

Expert Solution

Volume = v = 33.19 mL = 0.03319 L

Temperature = T = 23.43C = 23.43+ 273 = 296.43K

Pressure= P = 30.41 mm = 30.41/760 = 0.04 atm

Gas constant = R= 0.0821 L-atm/mole/kelvin

Ideal gas eqaution PV= nRT

number of moles of Oxygen   n = PV/RT

                                             n= 0.04 x 0.03319/0.0821x296.43

                                                = 0.0013276/ 24.3369

                                                  = 5.45 x10^-5 moles

Number of moles oxygen = 5.45x10^-5 moles
