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

11. Consider the following chemical reaction: CO2(g) + NaOH(aq) ---------> Na2CO3(s) + H2O(l) CO2(g) + KOH(aq) --------> K2CO3(s) + H2O(l) Carbon dioxide gas is bubbled into a 2.50 L. flask contains mixture of sodium hydroxide and potassium hydroxide. After evaporation of water and drying the mass of the residues is 14.5 g. Calculate grams of sodium hydroxide in the mixture. The pressure of carbon dioxide gas is 855 mmHg and the temperature is 25 oC. Na = 22.99 g/mole, K = 39.10 g/mole, H= 1.008 g/mole, O = 16.00 g/mole, C = 12.01 g/mole a.8.88 gb.1.19 gc.2.34 gd.3.48 g
In a 0.5 L container of gas at sea-level where the temperature is 298 K, the collision rate between molecules, Z, is 1.2 x 104 s. If the collision cross-section, o, of 9 × 10-19 m² remains unchanged, what is the change in collision rate if the temperature is cooled to 170 K? Note: the relative average speed is assumed to remain unchanged. 17
For the following reaction: C3H8(g) + 3CO₂(g) + 4H₂O(1) 502(g) The change in gaseous moles, An = To maximize the product yield, the volume of the container should ◆ , so that the pressure will be (> →
3. HNO is formed by NO₂ as follows. Calculate HNO3 concentration in µg/m³ at 1 atm pressure and 22 °C temperature for NO₂ concentration of 1 ppm. (MWs of N = 14, O = 16 H = 1 g/mol, R = 0.082 L.atm/mol.K) OH (g) + NO₂ (g) + M → HNO3 (g) + M
Based on the ideal gas law, there is a simple equivalency that exists between the amount of gas and the volume it occupies. At standard temperature and pressure (STP; 273.15 K and 1 atm, respectively), one mole of gas occupies 22.4 L of volume. What mass of methanol (CH3OH) could you form if you reacted 5.55 L of a gas mixture (at STP) that contains an equal number of carbon monoxide (CO) and hydrogen gas (H2) molecules?
2. Suppose the concentration of CO₂ in the atmosphere is 360 ppm. Convert this to g/m³ when temperature and pressure is 20°C and 100hPa..
Starting with the same mass of the following four solids, and the other reactant HCI(aq) being always in excess, which of the following would show the correct increasing order of the calculated ngas (either H2 or CO2), assuming all other parameters are held constant?

Oxygen gas formed by the decomposition of potassium chlorate was collected on the water. The volume of oxygen gas collected at 24 ºC and 762 mm-Hg pressure is 128 mL. Calculate the mass of potassium chlorate used in the reaction in grams. The pressure of the water vapor at 24 ºC is 22.4 mm-Hg. KClO3 (s) → KCl (s) + O2 (g)
