Magnesium plays a vital role in the function and structure of the body.
The adult human body consist of 25 grams of magnesium i.e. 0.25 % of the human body composition approximately.
Therefore, for a 60 kg adult, then the amount of magnesium in their body would be
= 0.15 kg
Convert kg to g:
1 kg = 1000 g
So, 0.15 kg = 
= 150 grams
Thus, amount of magnesium in 60 kg adult is equal to 150 grams
Answer:
Explanation:
Here, a balance between attraction between nucleus and electrons, and electron-electron, and nuclei-nuclei repulsion play role.
All chemical bonds are formed by overlapping of orbitals. If the electronegativity of the two elements forming the bond is very different (elements from the 1st ,2nd groups with elements of 7th group) then ionic bond are formed. If the electronegativities are more similar, then overlapping is stronger, and covalent bonds are formed.
Molar mass H₂O = 18.0 g/mol
1 mol ----- 18.0 g
3.5 moles --- ?
Mass ( H₂O) = 3.5 x 18.0 / 1
=> 63.0 g
