Carbon monoxide (CO) is a poisonous gas because it binds very strongly to the oxygen carrier hemoglobin in blood. A concentration of 8.00 × 102 ppm by volume of carbon monoxide is considered lethal to humans. Calculate the volume in liters occupied by carbon monoxide in a room that measures 10.99 m long, 18.97 m wide, and 11.89 m high at this concentration

The amount of CO that is occupied in the room is

Explanation:

We are given:

Concentration of CO = by volume

This means that of CO is present in 1 L of blood

To calculate the volume of cuboid, we use the equation:

where,

V = volume of cuboid

l = length of cuboid = 10.99 m

b = breadth of cuboid = 18.97 m

h = height of cuboid = 11.89 m

Converting this into liters, by using conversion factor:

So,  

Applying unitary method:

In 1 L of blood, the amount of CO present is

So, in of blood, the amount of CO present will be =

Hence, the amount of CO that is occupied in the room is

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
