Atmospheric scientists often use mixing ratios to express the concentrations
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): ppmv of X = vol of X at STP total vol of air at STP × 106 On a certain November day, the concentration of carbon monoxide in the air in downtown Denver, Colorado, reached 3.0 × 102 ppmv. The atmospheric pressure at that time was 628 torr and the temperature was 0oC.
a. What was the partial pressure of CO?
b. What was the concentration of CO in molecules per cubic meter?
c. What was the concentration of CO in molecules per cubic centimeter?
