The error Andrea mentioned is when you are calculating the number of moles of H2O (time stamp 7:48) 10.3 mol C3H8 x (4mol H2O/ 1 mol C3H8) = 41.2 mol H2O, not the 4.12 mol that is written. However your final calculation is still correct because you do not use this conversion to solve for your final answer.
I am not seeing this error in the video… can you be more specific (provide a time index?) I don’t see this error in the calculations after watching the video, but I might have totally missed it. I have for a final answer for the mass of H20 = 740 g.
We thought you might want to correct your mistake with your math (the decimal was wrong, it should be 41.2mol H2O, not 4.12mol H2O).
