Apharmacist attempts to weigh 100 milligrams of codeine sulfate on a balance with a sensitivity requirement of 4 milligrams. calculate the maximum potential error (nearest hundredth) in terms of percentage (%).
2) a 10-milliliter graduate weighs 42.745 grams. when 6 milliliters of distilled water are measured in it, the combined weight of graduate and water is 48.540 grams. by definition, 6 milliliters of water should weigh 6 grams. calculate the weight of the measured water and express any deviation from 6 grams as percentage of error (%, to the nearest hundredth).

4 %

2 ) 3.42 %

Explanation:

Sensitivity requirement of 4 milligram means it is not sensitive below 4 milligram or can not measure below 4 milligram .

Given , 4 milligram is the maximum error possible .

Measured weight = 100 milligram

So percentage maximum potential error

= (4 / 100)  x 100

4 %

2 )

As per measurement

weight of 6 milliliters of water

= 48.540 - 42.745 = 5.795 gram

6 milliliters of water should measure 6 grams

Deviation = 6 - 5.795 = - 0.205 gram.

Percentage of error =(.205 / 6 )x 100

= 3.42 %

e) none of the above answers are correct
