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 .

Answer: .3 or 3/10
Explanation: The probability that her first answer is correct is 2/5. Since she got the first guess correct, now there is only 1 correct answer out of 4. There is a 3/4 chance she will get the next problem wrong
So: 2/5 x 3/4 = .3
