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.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
