In the third trimester, amniotic fluid weight is approximately?

2 kilograms 1 kilogram 100 grams 1.5 kilograms

Correct Answer:

1 kilogram

Explanation:

Amniotic fluid volume increases as pregnancy progresses and is most around a liter near term. Since the fluid’s density is close to that of water, about 1 mL weighs ~1 g, so 800–1000 mL of fluid at term translates to roughly 0.8–1.0 kg. Saying “about 1 kilogram” captures this practical estimate for the third trimester. If the fluid were only a few hundred milliliters, the weight would be well under a kilogram, while volumes around two liters would exceed normal term levels.
