The Instructor recently had his car inspected by the KWIK Stocker State Inspection at Webster, Texas. The table below shows part of the Emission Test Results. Note that carbon monoxide (CO) and hydrocarbons (HC) are the two main exhaust gases produced by the combustion of gasoline-powered vehicles, and they are reported in different units.

What is the actual exhaust concentration of CO (MW = 28) at low speed emission test? Convert CO concentration from % into ppm and mg/m3.

Emissions Test Results
High Speed Emission Test Low Speed Emission Test
Standard Current Reading Standard Current Reading
HC (ppm) 220 17 220 51
CO (%) 1.20 0.11 1.20 0.16
CO2 (%) - 14.6 - 14.5
