Ответ:
0.8 L
Explanation:We are given:
Molarity of Ethanoic Acid in vinegar = 0.125 M
Number of moles of Ethanoic Acid = 0.1 mole
Finding the volume of the solution:
We know that the molarity of a solution is defined as:
Molarity = n / V (where n is the number of moles and V is the volume in L)
replacing the variables with the given values:
0.125 = 0.1 / V
Multiplying by V on both the sides
0.125V = 0.1
Dividing both sides by 0.125
V = 0.1 / 0.125
V = 0.8 L
Therefore, the volume of the solution is 0.8 L
