A bottle of mineral water weighs 450 (). Do you fill in volume unit or volume unit in brackets

Please explain the meaning of the words "net content 385 ± 5g" on a certain food package
The standard mass of this kind of food is 385g, the maximum mass is not more than 385 + 5 = 390 (g), and the minimum mass is not less than 385-5 = 380 (g)
