Answer: A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction or change the substance
Explanation:
Answer:
0.196 M
Explanation:
First, we have to calculate the moles of sodium hydroxide.
moles = mass / molar mass
moles = 3.9280 g / (39.997 g/mol) = 0.098207 mol
It is important to realize that even though 300 mL is the volume of water firstly added to dissolve the hydroxide, the flask is then filled to the mark, meaning that the volume of the solution is 500 mL = 0.500 L.
The molar concentration of sodium hydroxide is:
The concentration is an intensive property, that is, it does not depend on the amount of matter. As a consequence, the concentration of the 50 mL of solution in the buret is the same as the concentration in the flask.

peux tu me donner plus de précisions stp concernant le détail de calcul que tu souhaite avoir ?
Explanation:
During the mid 19th century, the country's natural resources were heavily exploited without any regard for the resulting waste that would be produce in the process. Forest land were being converted to industrial and residential areas. Mines were popping up to where rich minerals were present.
