- A water solution contains 60% Na2S202 together with 1% soluble impurity. Upon cooling to 10°C, Na2S202 • 5 H2O crystallizes out. The solubility of this hydrate is 1.4lb Na2S202 • 5 H20/lb free water. The crystals removed carry asadhering solution 0.06 lb solution/lb crystals. When dried to remove the remaining water (but not the water of hydration), the final dry Na2S202 5 H20 crystals must not contain more than 0.1% impurity. To meet this specification, the original solution, before cooling, is further diluted with water. On the basis of 100 Ib of the original solution,calculate (a) the amount of water added before cooling, and (b) the percentage recoveryof the Na2S202 in the dried hydrated crystalsAn aqueous solution is 3.50 % by mass hydrochloric acid, HCl, and has a density of 1.02 g/mL. The mole fraction of hydrochloric acid in the solution is ____.An aqueous solution of manganese(II) iodide has a concentration of 0.189 molal.

Round your answer to the thousandths place and do not include units.The prescriber ordered oxacillin 500mg IM q6h. The instructions on the 2g vial state to reconstitute the powder with "11.5mL of sterile water for injection, yielding 250mg/1.5mL" Whatis the strength of the reconstituted solution? How many milliliters would you administer?An aqueous solution of 0.2100 g of a mixture containing potassium cyanide and potassium chloride required 14.56 mL of 0.1000 M silver nitrate to produce a faint permanent turbidity; 30.00 mL more of the silver nitrate was added (an excess) and the precipitate of AgCl and AgCN filtered off from the solution. The filtrate and washings were titrated with 13.06 mL 0.1000 M thiocyanate solution. Calculate the percentages of KCl and KCN in the sample. Note: the appearance of faint turbidity indicates the formation of Ag(CN)2-
- It is recommended that children should have fluoride supple- ments for their teeth if the fluoride content of drinking water is 0.7 ppm or less.
