Answer
0.9166 g CO
Procedure
Considering the conditions and parameters given ideal gas law will be assumed.
The gas constant is 8.3144 L⋅kPa⋅ K⁻¹⋅mol⁻¹
Converting the current data to the required units
710 mL = 0.710 L
37 °C = 310.15 °K
Solving for moles and substituting the variables with the available data
Transforming from moles to grams using the molecular weight
