At the pool supply store when you buy chlorine it is like tablets/or pebbles you mix with the pool water. I kept getting it wrong but I just don't understand how it is a gas if it is something that dissolves in water?

114.7 mg of NaCl (MM=58.44 g) is dissolved in 246.42 L of water. What is the concentration of Na+ ion (MM=22.99 g/mol) in ppm? Give your answer rounded to four digits to the right of the decimal point. Hint: If you are stuck, calculate the %w/w of Na in NaCl using the molar masses - from pe106. Convert g to mg.

3. An important conversion factor that you must memorize and use in this course is: 1 mg/L = 8.34 lb/million gallons a) Start with a value of 1 mg/L and use dimensional analysis to prove that this conversion factor is correct: Show that 1 mg/L = 8.34 lb/million gal. b) A wastewater treatment plant adds 5 mg/L of a commercial polymer to raw water to enhance removal of colloidal particles during settling. If the flow rate of water into the facility is 100 MGD, how many pounds of polymer are needed each year? (hint, use the required conversion factor 1 mg/L = 8.34 lb/million gallon to perform the calculation)

1. Water is necessary for life on Earth. Water is made up of hydrogen and oxygen atoms (H2O); however, biological life in water depends on another form of oxygen. These organisms need molecular oxygen (O2), which they use to perform aerobic respiration. This molecular oxygen fits into spaces between water molecules and is available for aquatic organisms to use. How do you think molecular oxygen gets into the water? Choose two of the following choices. Select all that apply: From the oxygen atoms that are part of the water molecules. From oxygen that dissolves into water from the atmosphere. From oxygen that is given off by aquatic organisms during respiration. From oxygen that is given off by aquatic plants during photosynthesis.
Complete combustion of 10.98 g of a compound of carbon, hydrogen, and oxygen yielded 16.10 g CO2 and 6.592 g H₂O. When 6.780 g of the compound was dissolved in 261 g of water, the freezing point of the solution was found to be -0.805 °C. For water, Kfp = 1.86 °C/m. What is the molecular formula of the compound? Enter the elements in the order C, H, O molecular formula =
A geochemist in the field takes a small sample of the crystals of mineral compound X from a rock pool lined with more crystals of X. He notes the temperature of the pool, 24. C, and caps the sample carefully. Back in the lab, the geochemist dissolves the crystals in 3.00 L of distilled water. He then filters this solution and evaporates all the water under vacuum. Crystals of X are left behind. The researcher washes, dries and weighs the crystals. They weigh 45.0 g. Using only the information above, can you calculate yes the solubility of X in water at 24." C no If you said yes, calculate it. Be sure your answer has a unit symbol and 3 signiicant digits.
A pool contains 4500 gallons of 1.4% chlorine solution, which means that 1 4% of the liquid in the pool is actially chlorine: the rest is water. The goal is to find how many gallons of chlorine would need to be added to increase the concentration in the pool to 3%. Round your answer to the nearest gallon. ___ gallons would need to be added to increase the concentration in the pool to 3%
Calculate the volumes, in mL, of: ethanol, C2H5OH (ρ= 0.789 g/mL), that must be dissolved in water to obtain 2 L of 1.65M solution. -concentrated hydrochloric acid solution (HCl, 36% by mass, ρ = 1.18 g/ml) that mustdissolve in water to obtain 500 ml of 0.234 M HCl solution.
Please help I'm not sure how to solve these. A solution is prepared by dissolving 20g of NaCl (f.w.= 58.44 g mol^-1), a nonvolatile solute, in enough water (m.w. = 18.02 g mol^-1) to result in exactly 1 L of solution at 25 C. The density of the solution is 1 g mL ^-1. How do you calculate freezing point of the solution as well as vapor pressure and the osmotic pressure? I understand boiling point.
