2.3 M is the molarity of a solution that contains 2.3 moles of solute in 1.0 liter of solution.
Explanation:
Data given:
volume of the solution = 1 litre
number of moles of the solute = 2.3 moles
Molarity of a solution is given by number of moles of a given solute in a given volume in litres.
The unit of molarity = moles/litre
The formula used to calculate molarity is given by:
molarity =
Putting the values in the equation,
molarity =
molarity = 2.3
Thus the molarity of the given solution is 2.3 moles/litre.
The molarity of the solution is also written as 2.3 M.
The answer is A.)The final pressure of a gas is directly proportional to volume and temperature change.
