According to law of conservation of matter and energy, amount of both of them will remain same
Answer:
Explanation:
Option B is the correct answer
Answer:
0.4mol/L
Explanation:
Data obtained from the question include:
Number of mole of NaOH(solute) = 0.20 mole
Volume of solution = 0.50 L
Molarity =.?
Molarity is simply mole of solute per unit litre of a solution. This can represented mathematically as:
Molarity = mole of solute /Volume of solution
Molarity of NaOH = 0.2mol/0.5L
Molarity of NaOH = 0.4mol/L
Here is the graph, hopefully the next person can get it
Answer:
In chemistry the substance is usually measured using molecular mass and molar mass. They are very important concepts in chemistry. Expression of molar mass is grams per mole.
...
Molar mass:
Difference between Molar mass and Molecular mass
Measurement given to compounds, atoms or molecules Determined only in molecules
