The label on the bottle of vitamin says that each capsule contain 0.5 grams. when check each capsule had 0.505 grams. was that to little or to much. what the difference

0.505 g is more than the advertised amount by 0.005 g.

Step-by-step explanation:

0.5 = 0.500, so 0.505 is more than the advertised amount.

"Too little" or "too much" is a judgment based on some criteria not specified by the problem statement. Usually a supplier will want to ensure the customer receives full measure, so will adjust the capsule-making machine to provide at least the advertised amount. Whether it is "too little" or "too much" depends on your point of view and the dangers or costs of deviating from the advertised amount.

0.505 - 0.500 = 0.005 . . . . the difference between the actual and advertised amounts, in grams.
