A typical multivitamin tablet can contain 2.00mg of vitamin B2 (riboflavin), and the RDA is 0.0030 g/day. How many such tablets should a person take each day to get the proper amount of this vitamin, assuming that he gets none from any other sources?
1.5
To figure out how many tablets a person should take each day to get the proper amount of vitamin B2, we first need to convert the recommended daily allowance (RDA) from grams to milligrams.
Given:
- RDA of vitamin B2 = 0.0030 g/day
- Amount of vitamin B2 in one tablet = 2.00 mg
To convert grams to milligrams, we multiply by 1000:
0.0030 g/day * 1000 mg/g = 3.0 mg/day (RDA in milligrams)
Now, let's calculate how many tablets are needed to reach the RDA:
Number of tablets = RDA / Amount of vitamin B2 in one tablet
Number of tablets = 3.0 mg/day / 2.00 mg = 1.5 tablets
Since we are dealing with whole tablets, the person needs to take 2 tablets each day to meet the recommended daily allowance of 0.0030 g of vitamin B2.
To determine the number of tablets needed, we need to convert the Recommended Daily Allowance (RDA) for vitamin B2 from grams to milligrams.
1 gram (g) = 1000 milligrams (mg)
Therefore, the RDA for vitamin B2 can be expressed as:
0.0030 g = 0.0030 x 1000 mg = 3.0 mg
Now we can calculate the number of tablets required:
Number of tablets = RDA / Tablet content
Number of tablets = 3.0 mg / 2.00 mg
Number of tablets = 1.5
Therefore, a person would need to take 1.5 tablets of the multivitamin containing 2.00mg of vitamin B2 each day to obtain the proper amount of this vitamin.
