Atmospheric scientists often use mixing ratios to express the concentrations of trace compounds in air. Mixing ratios are often expressed as ppmv (parts per million volume): vol of X at STP ppmv of X = × 106 total vol of air at STP On a certain November day, the concentration of carbon monoxide in the air in downtown Denver, Colorado, reached 3.2 × 102 atmospheric pressure at that time was 625 torr and the temperature was 0°C. ppmv. The a. What was the partial pressure of CO? Partial pressure = torr b. What was the concentration of CO in molecules per cubic meter? Concentration = molecules/m3 c. What was the concentration of CO in molecules per cubic centimeter? Concentration = molecules/cm³
