Manganese makes up 1.3 × 10–4 percent by mass of the elements found in a normal healthy body. how many grams of manganese would be found in the body of a person weighing 196 lb? (2.205 lb = 1 kg) 56 g

Given the mass percentage of Manganese in a normal healthy body is

It means that g Mn is present in 100 g of the body mass.

Given that the person weighs 196 lbs

Converting the person's mass to g: The conversion factors to be used are: 1 kg = 2.205 lb; 1 kg = 1000 g

Calculating the mass of Mn in the person's body:

Therefore, 0.116 g Mn is present in a person weighing 196 lbs.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
