An aqueous solution was prepared by dissolving 4.93 g of KI in enough water to make 500.0 mL of solution.  What is the molarity of KI in the solution? (molar mass of KI:  166.00 g/mol)

Prompt 1:  Many individuals who log on to popular online social-networking sites, such as Facebook or Snapchat, see these as exciting new forums to express themselves, to encounter new ideas, and to socialize in the brave new world of cyberspace. The only rule on these sites seems to be that there are no rules, and their users seem to like it that way. However, another more ominous side of these new age meeting places has emerged recently. As a result of claims of assault and cyberbullying, many have called for closer regulation of popular computer networking sites and how those sites are made available to young people. Should these popular social-networking sites be regulated? Argue your position and propose solutions to fixing these issues involved with social media.   Prompt 2: Traditionally, our definitions of community have focused primarily on people who live or work near each other and who possess a sense of shared interests and values. This idea of community focuses on the connections people make with one another. In recent years, we have seen changes in media and social media (television, radio, Internet), technology (phones, email), and travel (cars, mass transit) and the effect it has had on our connections. In your opinion, are our notions of community enhanced or challenged by the new conveniences of social media networking, gaming, and other increasingly popular internet activities?
