Question

"You are told that the V of a solution is -2.2 but you really need to know the molar concentration. The solution is 20°C and it is in an open beaker"

A) 0.1 M
B) 0.5 M
C) 1.0 M
D) 2.0 M

Answer 1

The molar concentration of a solution cannot be determined with only the given information.

Step-by-step explanation:

The molar concentration (also known as molarity) of a solution can be calculated using the equation Moles of solute (M) = Molarity (M) x Volume (V) of solution. In this case, the question provides the volume of the solution (V) as -2.2. However, a negative volume is not physically possible, so we can assume that it is a typo and the volume of the solution is actually 2.2. To calculate the molar concentration, we need to know the number of moles of solute. Since the question does not provide information about the amount of solute, we cannot determine the molar concentration with the given information.
