Answer:
We need 0.375 mol of CH3OH to prepare the solution
Explanation:
For the problem they give us the following data:
Solution concentration 0,75 M
Mass of Solvent is 0,5Kg
knowing that the density of water is 1g / mL, we find the volume of water:
Now, find moles of 
are needed using the molarity equation:
therefore the solution is prepared using 0.5 L of H2O and 0.375 moles of CH3OH, resulting in a concentration of 0,75M
Explanation:
Advantages of Common Names
The main advantage of using common plant names is ease of usage and common understanding in certain geographical areas and, conversely, the prevention of confusion among the laymen who do not understand Latin
.What are the disadvantages of common names?
These names may not be same every where in all places so in order to have universally similar name.
Creates confusion among different languages.
Cannot identify one particular species by common names.
<span>As technology advances, new experiments often expose problems in accepted theories.
The advancement in technology allows scientists to explore more than previous scientists. Technology provides them with more tools to explore further. Technology can be used to prove or disprove old theories by uncovering more evidence. Fame has nothing to do with it, neither does excitement.</span>
