1 30.07 g C2H6 2 mol C2H6 1 mol H2O
When you complete this dimensional analysis you get that the answer is 482.17 g H2O

Yes ofcourse. This is a dimensional analysis problem.
So step 1, I started with the given value: 268.5 g C2H6. I then found the molar mass which is 30.07 g C2H6 = 1 mol C2H6. Then, I used the molar ratio to get the moles of H2O which is that 2 mol C2H6 = 6 mol H2O. I get this from the balanced equation. Then I find the molar mass of H2O so I can convert from moles to grams which is that 1 mol H2O = 18 g H2O. That’s the set up for the dimensional analysis.
Next I multiply everything in the numerator and I divide by everything in the denominator and that’s how I get the answer.
If you still need assistance with this question, let me know !
