While the average adult human body has at least 60 different elements present, carbon, oxygen, and hydrogen make up about 98% of all atoms. Potassium, an important electrolyte that helps regulate fluid balance, nerve impulses, and muscle contractions, is about 0.03% of all atoms present. If a person weighs 150-lbs and has approximately 7 x 1027 atoms in their body, how many of these atoms are phosphorus? (Show Your work.)
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Given,
% of Potassium atoms presents out of all atoms = 0.03 %
Total atoms in the body = 7 × 1027 atoms
NOTE: It is asked in the question of how many of these atoms are phosphorus? But since the information for Potassium atoms in our body is given, so it must be how many of these atoms are potassium?
The number of potassium (K) atoms in 7 × 1027 atoms can be calculated as :
