(a) Carbon monoxide
Interpretation:
The unit conversions are to be carried out by dimensional analysis for given measurements.
Concept introduction:
Dimensional analysis is used to set up and solve a unit conversion problem using conversion factors.
Dimensional analysis is a way to convert units of measurement. In order to convert one unit to another, the relationship between those units is to be predicted. These relationships are called conversion factors.

a)
b)
c)
Explanation of Solution
a) Concentration of CO
Dimensions of the room
Calculate the volume of the room.
The volume of the room is calculated as follows:
Now, calculate the volume occupied by CO in liters.
Set up the unit conversion calculation using the appropriate conversion factor.
The conversion is as follows:
The units in the conversion factor must cancel to give the correct unit for the answer.
Hence, the volume occupied by CO in the room is
b) The concentration of mercury vapor must be under

- The present average concentration (mass percent) of magnesium ions in seawater is 0.13%. A chemistry textbook estimates that if 1.00 × 108 tons Mg were taken out of the sea each year, it would take one million years for the Mg concentration to drop to 0.12%. Do sufficient calculations to either verify or refute this statement. Assume that Earth is a sphere with a diameter of 8000 mi, 67% of which is covered by oceans to a depth of 1 mi, and that no Mg is washed back into the oceans at any time.arrow_forwardWhich piece of equipment would you use to measure 7.10 mL of CuSO4 (aq)?arrow_forwardChlor-alkali plants electrolyze NaCl to produce the commodity chemicals caustic soda and chlorine gas.
