How many grams of magnesium would be a typical amount in a 60.kg adult?
Nata [24]

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

0.25\times \frac{60 kg}{100}

= 0.15 kg

Convert kg to g:

1 kg = 1000 g

So, 0.15 kg = 0.15 \times 1000 = 150 grams

Thus, amount of magnesium in 60 kg adult is equal to 150 grams
