The molarity is 0.001255. Should you really be asking an AP Chem question on Wiki Answers, anyways?

Is sulfuric acid a nonelectrolyte?
No, it is considered an electrolyte because charged ions are present, dissolved in solution (H3O+ and HSO4-). Any acidic aqueous solution is an electrolyte due to the presence of H3O+ in solution (similarly, any basic aqueous solution is also).
Why the more the volume of solvent thefaster sugar dissolves in water?
When enough sugar is dissolved into the solvent (water) , or goes 'in to solution' , that no more will dissolve , the solvent is said to be 'saturated'. The more solvent you have the more sugar you can put into solution. No more sugar will dissolve once the solvent (now your solution) is saturated.
What is the concentration of hydrogen ions in solution when 0.30 mol of nitric acid are dissolved in enough water to make 500.0 mL of solution?
H + and NO3 - are one to one, so no ratio needed here.Molarity = moles of solute/Liters of solution (500.0 mL = 0.5 Liters)M = 0.30 moles HNO3/0.5 L= 0.60 M H + ions in solution===================
What is formed when a solid dissolves in a solvent?
A solution, which means that there is two states mixed together (solid and liquid). It is technically a liquid, because area is stable but shape is no, but you can separate the solid from the liquid easily enough.
Where should you first be able to see the DNA in the solution?
You have not given enough information for your question to be answered. In what kind of solution is the DNA dissolved?

What is boiling out a solvent?
Boiling out a solvent is when you heat up a solution to a high enough temperature that the solvent (liquid) evaporates, leaving behind whatever you have dissolved.
Is sodium fluroide an elctrolyte?
Yes: If sodium fluoride is dissolved in water, the solution will conduct electricity, as will pure sodium fluoride if it is hot enough to melt.
Is tap water a solution?
In reality, yes, it is. Tap water contains dissolved minerals and gases. Certainly it is "clean" enough to drink, but there remain a number of dissolved elements and compounds that were not removed during processing. And there were a few things added, as well.
