Three teaspoons of sucrose(17.1 g) is dissolved in hot water to make a total volume of 250 ml solution. calculate the molarity

me by showing work

very confused on what to do

Molar mass sucrose :

C12H22O11 =  342.29 g/mol

number of moles of the solute :

n = mass solute / molar mass

n = 17.1 / 342.29

n = 0.05 moles

Volume in liters :

250 mL / 1000 =  0.25 L

therefore :

Molarity  =  moles of solute / volume

Molarity =  0.05 / 0.25  => 0.2 mol/L

It would be (at) + cu (s)
