Carbon monoxide (co) detectors sound an alarm when peak levels of carbon monoxide reach 100 parts per million (ppm). this level roughly corresponds to a composition of air that contains 400,000 /(/mu/)g carbon monoxide per cubic meter of air (400,000 /(/mu/)g/m3). assuming the dimensions of a room are 18 ft x 12 ft x 8 ft, estimate the mass (in grams) of carbon monoxide in the room that would register 100 ppm on a carbon monoxide detector. (1 meter = 3.28 feet)

19.61kg

Explanation:

The first thing to do is divide the amount of feet into 3.28:

With this information, we calculate the volume:

As we have the concentration and the volume, we can calculate the mass of CO:

As this is a very big number, we can express it in kg by dividing in 10^6:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
