Question

a 707 mg sample of gas containing only carbon and oxygen occupies a volume of 452 ml at 63 C and 745 mmHg. identify the gas in the sample (R= 0.0821 L*atm/K*mol)

Answer 1

a) CO
b) CO2
c) CO3 2-
d) C2O
e) C2O2

Answer 2

assuming the gas behaves as an ideal gas
\[n=PV/RT\]

\[M=m/n\]

summing up will give
\[M=mRT/PV\]
which works out to be CO2

Answer 3
