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

Calculate the molar mass of the following compounds in g/mol.<br> CH3CO2H

valentinak56 [21]

Answer:

60g/mol

Explanation:

By using nucleon numbers given on the periodic table, the mass of 1 mole of each element is:

C= 12g

H= 1g

O= 16g

Since molar mass is the sum of the masses of each element present in the compound,

Molar Mass (Mr) = 12+3(1)+12+16(2)+1 = 60g/mol
