The recommended daily value (RDV) of calcium for men and women between the ages 19 – 50 is 1000 mg. Powder milk contains 33.0% of the RDV per serving. The mass of a serving of powder milk is 24 g. What is the (wt/wt %) of calcium per serving of powder milk?
Homework Answers
total mass of milk powder 24 g
let the mass of calcium be x gm in the milk powder
percentage of calcium in the milk powder P = x/24 *100
given P =33
33=x/24*100
33/100 =x/24
.33*24 =x
7.92 g= x
7.92 gis the (wt/wt %) of calcium per serving of powder milk?

Many individuals increase their Caintake by taking calcium supplement tablets containing CaCO3. A bottle of 60 tablets costs $3.98 and contains 3.175 ounces of calcium supplement tablets. Each tablet has a total mass of 1.500 grams and contains 600.0 mg of Ca. a) Using the unit cost, calculate the cost per ounce of the calcium supplement. How does this cost per ounce compare to the cost per ounce of the dried milk powder? 84.95 adig) n. 175o2 = 41.25 Peroz...

The NIH advises women ages 19 to 50 to consume 1,000 milligrams per day of Calcium, which is nearly impossible without dairy. But the World Health Organization suggests just 400 to 500 mg of calcium per day for all adults, or roughly the amount you'll get if your meals include kale, beans, oatmeal, tofu, broccoli, or other calcium fortified foods like orange juice. Why do you think that these recommendations are so different? What does research suggest the recommendations should...

A health administration recommends that individuals consume 1000 mg of calcium daily. After an advertising campaign aimed at male teenagers, a dairy association states that male teenagers consume more than the recommended daily amount of calcium. To support this statement, the association obtained a random sample of 50 male teenagers and found that the mean amount of calcium consumed was 1020 mg, with a standard deviation of 150 mg. Is there significant evidence to support the statement of the association...
