<h2>
Answer:</h2>
1.24kg
<h2>
Explanation:</h2>
Given;
Mass of the man (M) = 195 pound
<em>First, convert the value to kilograms (kg) as follows;</em>
Note that;
1 pound = 0.453592kg
Therefore,
195 pounds = 195 x 0.453592kg = 88.45kg
<em>Now, since the mass of calcium (say m) in a human body is 1.4% of the mass (M) of the body;</em>
=> m = 1.4% of M
=> m = 1.4% x M ------------------(i)
Where;
M = 88.45kg
<em>Substitute the value of M into equation (i) as follows;</em>
=> m = 1.4 % x 88.45
=> m = (1.4 / 100) x 88.45
<em>Solve for m;</em>
m = 0.014 x 88.45
m = 1.24kg
Therefore, the mass of calcium in the 195-pound man is 1.24kg.
