Answer: 1 tablet per day
Step-by-step explanation:
Given:
Mass of vitamin B2 in the tablet = 3.00mg = 0.003g
Daily requirement = 0.0030g/day
To get proper amount of vitamin ( not too much or too low), the number of tablets to take per day is given as;
N = mass per tablet/daily requirement
N = 0.003g/0.003g/day
N = 1 tablet per day
Therefore, a person should use one tablet per day.
