Multi-stage flash distillation is used to desalinate seawater so it is fit for human consumption. a flash distillation tank is composed of small chambers (called \"stages\"), each at a lower pressure than the previous stage. salt water enters the first chamber, some fresh water flash evaporates, condenses, and is removed from the distillation tank. the remaining salt water moves to the next chamber, some fresh water flash evaporates, condenses, and is removed from the distillation tank. the remaining salt water moves to the next chamber, and the process repeats until very salty water is expelled as waste. brine that is 35,000 ppm salt is desalinated through a 5-stage flash distillation process. the pressure in the stages is such that 8% by mass of the water entering the stage evaporates and leaves as fresh water. if the desalination plant wants to produce 1400.0 gallons of drinking water per day, how many gallons of brine must the plant take in per day? the density of fresh water is 1.000 g/cm3. the density of brine is 1.025 g/cm3.

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5
