Taking into account the definition of molarity, the concentration of CH₃OH in the solution is 3.12 .
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
Molarity is expressed in units .
<h3>Concentration of CH₃OH</h3>
In this case, you know:
- number of moles= 50 g× = 1.56 moles, being 32.04 the molar mass of CH₃OH
- volume= 500 mL= 0.5 L (being 1000 mL= 1 L)
Replacing in the definition of molarity:
Solving:
<u><em>Molarity= 3.12 </em></u>
Finally, the concentration of CH₃OH in the solution is 3.12 .

Explanation:
A n example of Lesson 16.2 modeling exponential growth and decay is find out if y =5(2)ˣ is exponential growth or decay.
<h3>How do you know an exponential growth or decay?</h3>
One can know if a function is an exponential growth or decay when it has a as positive and b is said to be greater than 1 (to be exponential growth).
If a is said to be positive and b is said to be lower than 1 but when it is also greater than 0, we can say that it is an exponential decay.
From the above, y =5(2)ˣ is an exponential growth because the base is said to be greater than 1 and the exponent contain a positive notation.

The correct answer is "Section 1910" Hope this helps.
Please mark me as brainliest if it did. Thanks.
Answer: Negative, Positive
Explanation:
Cations lose electrons to get a positive charge, while anions gain electrons to get a negative charge.
