Question: weight of a 12 oz soda can?
Answer: As a check, I googled “weight of can of coke” and it gave me 382g for a 12oz (355ml) can. You asked about a 330ml can so we need to multiply 382g by the ratio 330/355, which gives us 355g, which agrees well with our first answer. What's 50 mL of syrup converted to grams? Does 1 oz of water weigh 1 oz?
