A solution of concentrated NaOH is 16.4 M. If the density of the solution is 1.43 g/mL what is the percent by mass NaOH? What is the density of an aqueous solution that has a mass of 10.081 g and a volume of 12.5 mL? A 10.00 wt% HCl(aq) solution has ...
Why must solutions involving percent-by-volume (i.e., V/V and m/V) be prepared by reaching a final volume of the solution rather than adding the volume of the solute and solvent? What is the molarity of a solution in which 55.49 g of calcium chloride is dissolved in enough water to ...
As the strong acids become more concentrated, they may be unable to fullydissociate. The rule of thumb is that astrong acidis 100 percent dissociated insolutionsof 1.0 M or lowerconcentration. Dissociation and pKa Values The general form of the dissociation reaction of a strong acid is as foll...
With percent mass measurements, the math will be more complex if the solvent is not water because water has a convenient density of 1g/ml. When dealing with concentration gradients that affect the movement of water or particles, it is important to know the total number of particles per unit ...
City Dust 24% City dust, which accounts for 24 percent of microplastics in the oceans, comes from a variety of sources. While each is a small contributor, it adds up in a opulated area. City dust includes losses from the abrasion of objects like synthetic soles of footwear, synthetic ...
clean barley (Horbeum vulgare or hordeumdistichon). It must be whitish in color and be free from fermented, musty or other objectionable taste or odor, adulterants and insect and fungus infestation and rodent contamination. It shall not contain other food grains more than 1 percent by weight....
Eighty percent of our immune system resides in our gut, so it makes sense that sub-optimal gut flora would cause an ill-functioningimmune system. When gut bacteria isn’t optimal, baby’s immune system is not going to be optimal. That means baby will be more likely to catch colds, flus...
Statistics on use have it anywhere from 70-80% percent of the pro bodybuilding and bulking communities use HGH or supplements while weightlifting, weight training, and cross fitness regimens. Because it does not show up on urine tests like anabolic steroids it is probably even more widely used,...
Why should the buret be rinsed with NaOH before it is filled? Why does a pink color appear, and then disappear quickly, at the point where the NaOH solution comes in contact with the solution in the What are some causes of a high percent error when titrating Ca(OH)2 with HCl and phen...
