It looks like you're listing quantities of certain items in grams. However, without context or information on what each quantity pertains to, I can only provide arithmetic operations. If you're looking to add them up:
450 grams + 450 grams + 55 grams + 55 grams + 35 grams + 35 grams + 45 grams = 1125 grams
If you're looking to find out something specific about these quantities, please provide more details or context.
450 grams 450 grams 55 grams 55 grams 35 grams 35 grams 45 grams
