2.50 Molar

Molarity is defined as the number of mole of solute per liter of solution,

Mathematically,

#M = (n/V)#

#M = (2.5 / 1.00 )#

#M = 2.5 Molar#

#2.5 \ "M"#

Molarity is expressed through the equation

#"molarity"="moles of solute"/"liters of solution"#

Here, the solute is salt, and the solution has a volume of #1 \ "L"#.

So, the molarity is

#"molarity"=(2.5 \ "mol")/(1 \ "L")=2.5 \ "M"#

Note: We use #1 \ "M"# to represent #1 \ "mol/L"#.
