Answer:
1) 0.18106 M is the molarity of the resulting solution.
2) 0.823 Molar is the molarity of the solution.
Explanation:
1) Volume of stock solution = 
Concentration of stock solution = 
Volume of stock solution after dilution = 
Concentration of stock solution after dilution = 
( dilution )
0.18106 M is the molarity of the resulting solution.
2)
Molarity of the solution is the moles of compound in 1 Liter solutions.
Mass of potassium permanganate = 13.0 g
Molar mass of potassium permangante = 158 g/mol
Volume of the solution = 100.00 mL = 0.100 L ( 1 mL=0.001 L)
0.823 Molar is the molarity of the solution.
There's no reason, it's just because the sun has a gravitational pull
Answer:
yes
Explanation:
is that is the alteration of a planet on its orbit around the sun depends upon the mass of the Sun and the inverse square of the planets distance from the Sun. As a planet moves further away in its orbit around the Sun, the gravitational force exerted by the sun on the planet decreases
Answer: New concentration of 
is 0.23 M.
Explanation:
The given data is as follows.
Moles of = 0.06 mol
Moles of 
= 0.08 mol
Therefore, moles of 
added are as follows.
Moles of = 
= 0.003125 mol
Now, new moles of = 0.06 + 0.003125
= 0.063125
Therefore, new concentration of will be calculated as follows.
Concentration = 
= 0.23 M
Thus, we can conclude that new concentration of is 0.23 M.
Answer:
Explanation:
Hello.
In this case, since the chemical reaction is:
We next compute the moles of sodium carbonate from the 2.00 grams of calcium carbonate via their 1:1 mole ratio in the chemical reaction:
Thus, by knowing the molarity, we compute the volume:
Best regards.
