Water pollution, also known as the contamination of water bodies, was a major issue and it still continues to be in our world today. People need to pay more attention to this problem because it is harming the environment. By harming our environment, we are also endangering our health. As soon as humans intake bacteria and parasites, they’re more likely to be infected with diseases and viruses. Humans are not the only ones being harmed, but so are animals, especially water animals. Marine life is affected immensely by the impurity of these seas and oceans due to the fact that it causes them to live in an unhealthy environment where they are also exposed to diseases. In addition to that, water animals, such as fish, can find pollutants, some…show more content… It contains a high amount of pollutants that are still increasing to this day. The harmful effects of these contaminants are very severe that they’ve caused the extinction of the Baiji dolphin population back in 2008. Due to industrial development, the river is completely polluted. Moreover, the amount of fish continues to decrease each year (Fishing and Pollution in Yangtze River, n.d.). Picking out a sample of water from the river, I found 0.21 mg of ibuprofen, 3 g of corn oil, and 1 g of sand, among other pollutants. These could definitely damage the environment and harm the community of people living along the…show more content… To find the molarity of the ibuprofen, we convert the 0.21 mg into grams then into moles. We divide 0.21 by 1000 and we get 2.1 x 10-4 g. Next, we divide 2.1 x 10-4 g by the molar mass of ibuprofen, which is 206.31 g/mol, and we get 1.02 x 10-6 mols. The sample is 40 mL and we need that amount in liters, so we divide by 1000 and we get 0.04 L. Finally, we divide the amount of moles (1.02 x 10-6) by the amount of liters (0.04) and we get the molarity of 2.55 x 10-5 M. Oils are made up of molecules called triglycerides. The chemical formula of triglyceride is C55H98O6 (Triglyceride, n.d.). To find the molarity of the corn oil, we convert the 3 g into mols. So, we divide 3 g by the molar mass of corn oil, which is 855.53 g/mol, and we get 0.0035 mols. Then, we divide the amount of moles (0.0035) by the amount of liters (0.04) and we get the molarity of 0.088
