  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The statement claims 'The density of water is 1.0 grams.' Density is defined as mass per unit volume and requires units like g/cm³ or g/mL. While water's density is approximately 1.0 g/cm³ at 4°C, stating it as '1.0 grams' is dimensionally incorrect - grams measure mass, not density. The correct answer is False because density cannot be expressed in grams alone.

AI explanation

The statement is false as worded because 'grams' is a unit of mass, not density -- density needs a mass-per-volume unit such as g/cm³ or g/mL. Water's density is indeed approximately 1.0 g/cm³ (or 1000 kg/m³) at standard conditions, but simply saying 'the density of water is 1.0 grams' is dimensionally incorrect/incomplete, making the statement as given false. This tests attention to correct units, not just the numeric value.
