Answer:
400 mg
Explanation:
Given:
A woman with is told by her doctor to take 1,000 mg of calcium carbonate.
Question asked:
How many mg of calcium are in this 1,000 mg regimen of calcium carbonate?
Solution:
As we know:
Amount of elemental calcium in a medicine containing calcium carbonate = 40%
As here doctor prescribed 1000 mg of calcium carbonate to be taken by the woman increasing intake of calcium-containing foods in her diet and including regular weight-bearing exercise, hence amount of elemental calcium in 1,000 mg regimen of calcium carbonate will be,
[tex]40\%\ of\ 1000\ mg\\\frac{40}{100} \times1000\ mg\\\frac{40000}{100} = 400\ mg[/tex]
Therefore, 400 mg of calcium are in this 1,000 mg regimen of calcium carbonate.
