Environmental Engineering Question, Please show all your work!!! ignore the BEER part, that is for a different problem.
2. Consider that all of the water that passes through our bodies eventually ends up in the well-mixed hydrosphere of the Earth. Consider an individual living during biblical times two thousand years ago. All of the water that was consumed by that individual and excreted in various ways is now spread throughout the oceans and freshwater lakes of the world. Assuming that the oceans and the rest of the hydrosphere have been completely mixed over the last 2000 years, approximately how many water molecules that passed through that individual would you expect to find in a 1 6-ounce glass of water today?? You can make the following assumptions: Life expectance in O AD = 30 years. Healthy rate of water consumption = 8 L/day Total volume of the oceans and hydrosphere is 1.4 x 10^9 km^3 Avogadro?s # = 6.02 x 10^23 molecules/mole Molecular weight of water = 18 g/mol. Assume that the beer has the same density as water (1 kg/E, e.g. Coors).Explanation / Answer
Approximately 80,000 water molecules in a 16-ounce glass of water today.
