if you place 13 grams of KCl into 1500 ml of H20, what is the molarity?...
Dilute 1500 mL of 0.5 M KCL to a final volume of 3L. what is the resulting molarity?
What Molarity of NaCl would give a 300mOsm solution so as to be isotonic to ECF and ICF Set up and solve for X: (cross multiply) 300 mOsm X 2000 mOsmTM Try this on your own, then read on. Show work here: You should have an answer of 0.15 M. If you don't: please ask for help. You need to be able to get that calculation for the next part. Now find the number of grams per liter needed to...

5. The solubility of KCl (in grams KCl/100 g of water) is 31.0 g at 10.0 °C, 34.0 g at 20.0 °C, 42.6 g at 50.0 °C, and 56.7 at 100 °C. a) You want to make a saturated solution of KCl at 50.0 °C using 2.00 L of water. How many grams of KCl are necessary to make this solution? You may assume that the density of water is 1.00 g/mL. b) You then take your saturated solution of...
please just tell me clearly what goes in each box. thank you! 115 grams of KCl is dissolved in 750 ml of water (assume density = 1.005 g/ml). What are the molality, molarity, mole fraction, mole percent, % mass, ppm by mass? What would be the freezing point and boiling point of that solution assuming the Kf of water is 1.86 oC/m and Kb is 0.512 oC/m (assume that KCl fully dissociates with no pairing of ions)? f. PPm by...
