Discussion Overview
The discussion revolves around calculating the mole ratio of water to copper sulfate based on given quantities of each substance. It includes considerations of empirical formulas and the challenges of deriving integer ratios from experimental data.
Discussion Character
- Homework-related, Mathematical reasoning, Conceptual clarification
Main Points Raised
- One participant asks how to find the mole ratio between 0.283 moles of water and 0.503 moles of copper sulfate.
- Another participant suggests dividing the numbers but expresses uncertainty about whether this addresses the original question.
- A different participant proposes that the ratio should be adjusted to yield natural numbers, indicating a need for integer representation.
- One participant reiterates the need for integer ratios and notes that the specific numbers provided do not lead to a straightforward solution.
- Another participant mentions that errors in experimental measurements could affect the data being analyzed.
- A later reply indicates that the original poster has received help and feels more confident in their understanding of the empirical formulas involved.
Areas of Agreement / Disagreement
Participants express differing views on how to approach the calculation of the mole ratio, with no consensus reached on the best method. Some acknowledge the complexity of deriving integer ratios from the given values.
Contextual Notes
There are indications of potential errors in experimental measurements that could impact the calculations, but these are not resolved within the discussion.

Dividing the numbers.
I don't think that's the answer you are looking for, but I have no idea what the real question is.

You need to multiply or divide (EXCLUSIVE OR) the ratio by 1 so that each part is a natural number, or as close to natural numbers as reasonably possible.

I am sure that's not what you have aimed at. Multiplying or dividing by 1 doesn't change the situation
My first idea was too that sweet should look for integer ratio, but numbers shown (283/503) lead nowhere.

1 is a rational number which can be expressed as N/N for any real number N.
I did not actually try to solve the original poster's question; only offered a commonly used suggestion. If he is trying to process experimental measurements, some of the data could have errors, even somewhat small errors.

ok, I think i got it now, we had to use emperical formulas, my teacher helped me out a little bit, now i think i know what I am doing...
