What is the molarity of a solution that contains 2.3 mol of solute in 1.0 liter of solution? PLEASE HELP

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.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
