Final answer:
The question is a chemistry problem where the answers pertain to calculations involving concentrations or masses of substances, and the need to use significant figures. Final answers such as (a)700, (b)1.0, (c)0.34gI2/L represent rounded values according to significant figure rules, indicating precision in reported results. It is important to ensure final answers match options specified in the question.
Step-by-step explanation:
The question appears to be related to a chemistry problem, specifically focusing on the calculation of a substance's concentration or mass in a solution, and the proper application of significant figures in those calculations. When you are given a series of calculations, such as determining the mass of HC1, the density in g/mL, the volume of a substance in liters, or the amount of a substance in moles or grams, you need to ensure that your final answer is reported with the correct number of significant figures. In the case of the answer being (a)700, (b)1.0, (c)0.34gI2/L, these numbers appear to represent the final result to the problem, rounded to the appropriate number of significant figures, although the context of the problem is not provided.
In chemistry, significant figures are used to express the precision of a measurement or calculation, and when a sequence of calculations is performed, the final answer should be limited to the least number of significant figures used in any of the measured values. For example, if we look at the density calculation given, the result is 0.866728... g/mL which is rounded to 0.867 g/mL when limited to three significant figures. This is critical as it indicates a measured value's precision and ensures that the reported result does not imply greater accuracy than the measurements allow.
The answers provided, such as 0.867 g/mL, 5561 L, or the mass of a solute in a glucose solution, all represent examples of final answers in chemistry problems, where the calculation process involves adhering to significant figures rules. Each value, whether it is given in kilograms, grams, liters, or moles, should reflect the precision of the measurements involved in the calculation. Please mentioned the correct option in final answer is an important reminder to always check that the result you present matches the option requested in any multiple-choice or similar format questions.
