Answer: 1.418 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: 135 g

molar mass of solute: 95.21 g/mol

let's plug it in:

[tex]\frac{135 g}{95.21 g/mol} = 1.418 mol[/tex]

next, we plug it into our original equation:

[tex]\frac{1.418 mol}{1.0 L} = 1.418 M[/tex]
