Answer:
The moles of solute
Explanation:
When you make a dilution, moles of solute does not change when you add solvent.
In concentrated solution, you have x moles of solute, that will be the same in the diluted solution.
Relation between molarity or volume of concentrated and diluted solutions is called, "dilution factor".
When you calculate the dilution factor: you use this formula
Molarity concentrated . Concentrated volume = M diluted . Diluted volume
M concentrated / M Diluted = Diluted volume / Concentrated volume
D.
A more accurate answer would be -50 m/s. 50 m/s is the change in speed.
The scientific meaning of salt is an ionic compound that is formed when an acid and a base reaction take place and is neutralized.
The common meaning of salt (table salt) is specifically the organic mineral of sodium chloride (NaCl) and is digestible.
Ionic salts are often not digestible (or not commonly digested, anyway)
Answer: There are 0.0637 moles present in 85.0 mL of 0.750 M KOH.
Explanation:
Given: Volume = 85.0 mL (1 mL = 0.001 L) = 0.085 L
Molarity = 0.750 M
It is known that molarity is the number of moles of solute present in liter of a solution.
Therefore, moles present in given solution are calculated as follows.
Thus, we can conclude that there are 0.0637 moles present in 85.0 mL of 0.750 M KOH.
