The Molarity
concentration is expressed in units of moles / L. So let us first determine the
number of moles of CH3OH, and then divide that amount by the total volume of
0.230 L of solution.<span>
<span>To determine the number of moles of CH3OH, divide the weight
in grams of CH3OH by the molecular weight of CH3OH: (MW of CH3OH = 32
g / mol)</span>
number of moles = 16.8 g / (32 g / mol)</span>
number of moles = 0.525
mol CH3OH <span>
Then we calculate for molarity:</span>
Molarity = 0.525 mol
CH3OH / .230 L
Molarity = 2.2826 mol /
L
<span>Molarity = 2.28 M</span>
Answer:
The more reactive the metal, the more rapid the reaction is. A metal below hydrogen in the reactivity series will not react with dilute acids.
Explanation:
Answer: The final molarity of the diluted oxalic acid solution is 0.0032 M
Explanation:
Molarity: It is defined as the number of moles of solute present per liter of the solution.
Formula used :
where,
n= moles of solute
Moles=
= volume of solution in ml
To calculate the final molarity of the diluted oxalic acid solution
where,
are the molarity and volume of concentrated oxalic acid solution.
are the molarity and volume of diluted oxalic acid solution.
We are given:
Putting values in above equation, we get:
Thus the final molarity of the diluted oxalic acid solution is 0.0032 M
I believe that the answer to the question provided above is that molecules in solid are compact and are connected. It requires huge energy to move it, thus requires high temperature.
