The correct answer to this open question is the following.
Although you did not attach options for this question, we can say the following.
The original (first) covenant God made with Abraham was the promise of God to bless the descendants of Abraham. God blessed Abraham and told him that he was going to be the "father" or leader of many tribes. In Genesis, the first book of the Old Testament, God told Abraham to travel to the promised land of Cannan, but he had to make sure that his people would be faithful and loyal to God.
In comparison, the Second Covenant is the one that is referred to in the New Testament, when God, who loves his creatures, sent his own son Jesus to help humans. God promises humans that he will forgive all their sins if they followed Jesus' teachings.
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 .
