The directions state "weigh about 5 grams of sodium chloride". Give minimum and maximum amounts of sodium chloride that would satisfy these instructions.
You don't provide enough data to give an accurate answer but usually these problems would indicate about 4-6 grams.
If this is a titration problem you want enough to use about 35-45 mL of the titrant. If a grqavimetric procedure it depnds upon what kind of balance you used. Does it weigh to the nearest 0.1 mg or to the nearest 0.0001 mg.
To determine the minimum and maximum amounts of sodium chloride that would satisfy the instructions to weigh about 5 grams, let's start by understanding what "about" means in this context. "About" implies a certain level of flexibility or approximation. In this case, it suggests that the actual weight of sodium chloride can be slightly more or less than 5 grams.
To find the minimum and maximum amounts, we can establish a range based on the tolerance for approximation. Typically, a range of ±5% is considered reasonable for such instructions.
Step 1: Calculate the 5% tolerance range:
5 grams × 0.05 = 0.25 grams
Step 2: Calculate the minimum and maximum amounts:
Minimum amount of sodium chloride = 5 grams - 0.25 grams = 4.75 grams
Maximum amount of sodium chloride = 5 grams + 0.25 grams = 5.25 grams
Therefore, the minimum amount of sodium chloride that would satisfy the instructions is 4.75 grams, and the maximum amount is 5.25 grams. Any weight within this range can be considered acceptable for the given instructions.
To weigh about 5 grams of sodium chloride, there is a range of possible minimum and maximum amounts that would meet this requirement.
The minimum amount would be slightly less than 5 grams, while the maximum amount would be slightly more than 5 grams.
However, since the instructions only mention "about 5 grams," it is acceptable to provide a slightly smaller or larger amount as long as it is approximately close to 5 grams.
Therefore, the minimum amount could be around 4.9 grams, and the maximum amount could be around 5.1 grams.
