What is the definition of a solute?
Don't really know.....you should ask someone
Could you calculate the molarity of a solution you need to know the moles of solute and the?
volume of the solution
What do you use universal indicator solution for?
It is a chemical solution used for knowing the pH of a substance. Eg. You mix a drop of Universal indicator solution with approx 5 mL of the substance whose pH you want to know.You can compare the color with a standard pH chart and know the pH.
What did people think about Alfred wegener's theory?
some people didnt believe alfred wegener because he didnt have all the info the scientist wanted. like if they asked him a question about his theory on pangea and he didnt know then how could he have the evidence on the continental drift so yeah if they asked him a question he wouldnt know and thats what my collage teacher said but im now in university and not studing that so :)

Can the density of a solution be used to determinr how much substance is dissolved in it?
yes, you just need to know the volume

What are solvents also know as?
A solvent is a compound that can dissolve another substance. As far as my knowledge they do not have another word to describe it unless you want to say the solution that does the dissolving. In case you want to know, the substance that gets dissolved is called the solute

Iron nail dipped in copper sulphate solution?
When an iron nail is dipped in the solution of copper sulphate solution , after a while the solution changes into the colour of green becoming iron sulphate and a brown substance is found on the iron nail which is copper so we get to know that the displacement reaction is produced
What was the worst thing about living in the middle ages?

Compare and contrast pure substances and solutions?
It can be quite difficult unless you know the properties of the pure substance in the solution. For instance, image you have a solution that is water-based. The boiling point of water under standard conditions is 100 °C. If you measure the boiling point of a water-based solution, it will and your mother will not have the same boiling point (the presence of ions in the water will raise the boiling point). You could also measure other properties, such as the density, freezing point, color or absorption spectrum, NMR spectrum, elemental weight percent, etc. using a variety of analytical methods. However, none of these methods will do much good unless you have a good idea what the solution might be composed of. If not, the task is extremely challenging!
