I need help with a problem that should be solved in a similar way to the example problems, but the answer is slightly different. Thank you!

This afternoon, I used Pro2 to work through an example, following the steps in the example one by one. However, I noticed that there were still some differences in the results. There was only one aspect that was unclear: for one of the gas components, the value given wasn’t density but rather specific gravity, which is a relative value. So I multiplied that value by 1000 Kg/m^3. I’m not sure if this approach is correct Could you give me some advice, senior? Thank you! !
This is generally the right approach, but it should be kept in mind that the density of water at different temperatures and pressures is not necessarily 1000! !
I’ve also worked on the example problems, and there are indeed some differences; they should be within the acceptable range of error. I look forward to hearing from experts
The gas composition provides not density, but a specific gravity, which is a relative value. I then multiplied that by 1000 Kg/m^3. The difference between specific gravity and density isn’t 1000; it’s g, where g=9.8
