for the molecular formula I got C48 H78 N6 O12 but when i googled it, it was C49 not C48, did anyone else get that?

I got C49. I found the mass percentages and then found the moles of C out of 100. g to get 5.20 mol C. Then, I divided by the smallest amount of moles (0.637 moles N) to get 8.16 as the ratio of C. When I multiplied that by 6, I got C49. Maybe your ratio or one of the intermediate calculations was slightly off? It may also just have been a rounding error.

Hope this helps!
