Approximately how many grams does 1 milliliter of pure water weigh?

Explanation:
The idea being tested is how mass relates to volume through density. For pure water, density is about 1 gram per milliliter at typical lab temperatures. Since 1 mL equals 1 cubic centimeter, that volume of water weighs roughly 1 gram. In more precise terms, water density is about 0.998–0.999 g/mL at room temperature and about 1.000 g/mL near 4°C, so 1 mL is essentially 1 g.
