Is a glass of water equal to 30 grams or 300 grams?

More likely 300 grams. 30 grms would be nearly two tablespoons.

To determine the weight of a glass of water, we need to know the size of the glass. Typically, a standard glass of water is considered to be 8 ounces or 240 milliliters.

Water has a density of 1 gram per milliliter (g/mL) or 1 kilogram per liter (kg/L). Therefore, the weight of 240 milliliters of water would be 240 grams.

So, a glass of water would weigh approximately 240 grams, which is closer to 300 grams than 30 grams.
