Answer:  1.997 M

Explanation:

molarity = moles of solute/liters of solution or [tex]M = \frac{mol}{L}[/tex]

first we have to find our moles of solute (mol), which you can find by dividing the mass of solute by molar mass of solute

mass of solute: 92 g

molar mass of solute: 46.08 g/mol

let's plug it in:

[tex]\frac{92 g}{46.08 g/mol} = 1.997 mol[/tex]

next, we plug it into our original equation:

[tex]\frac{1.997mol}{1 L} = 1.997 M[/tex]
