the directions state weigh about 5 grams of sodium chloride. Give minimum and maximum amounts of sodium chloride that would satisfy these instructions.
Ans - We can say that weighting depends of device you are using. The instruction indicates that the measured quantity of the sodium chloride must be less than or grater than 5g. There should be a range of sodim chroride measured.This will give us an fix number rather than significant figure with decimal range of .001. It should not be that the maxium limit is very high and minium limit is very samall like 8 to 2. So we shoild thake a certain limit of maximum and minimum amount.
Maximum = 5.2
Minimum = 4.8
This can satify the Instructor as it 5+- 2
5 plus minus 2 is the best amiunt which will satisfy the instructor.
