What is the concentration in µg/L and in ppb (parts per billion) and in moles/L? To find the concentration in ppb we need the weight of the water. = 7.7 µg L 23 µg 3 L 10 Docsity.com Standard assumption: density of water is 1g/ml or 1000 g/L (at 4°C). 7.7 × 10−6g 1 L × 1 L 1000 g = 7.7 × 10−9 = 7.7 109 = 7.7 billion = 7.7 ppbm ➭ For density of water is 1000 g/L, 1 μg/L = 1 ppbm 1 mg/L = 1 ppmm 11 Docsity.com
