Which element makes up 1/400 of the human body ? Magnesium, Potassium, Sodium, or Sulfur
Answer:
A. Magnesium.
Step-by-step explanation:
We are asked to find element which makes up 1/400 of the human body.
Let us convert 1/400 to percentage.
\(\frac{1}{400}\times 100\%\)
\(\frac{1}{4}\%\)
\(0.25\%\)
We know that amount of magnesium in human body is approximately 0.25%, therefore, Magnesium makes up 1/400 of the human body.
