Answer:125.84g

Explanation:Sucrose is dissacharides an organic compound in the class of carbonhydrate with the chemical formula C11H22O11. molar concentration is given by number of moles/Volume, this implies that moles=molar concentration * Volume=0.130M*2.75L=0.3575moles.

Furthermore, number of moles=Mass of Sucrose/molecular Mass of Sucrose.

From it's formular C11H22O11, molecular Mass is the addition of the mass number which is 12 for C, 2 for H and 16 for oxygen, O. so molecular Mass of Sucrose is (12*11) + (2*22) + (16*11) = 352.

So mass = moles * molecular mass=0.3575moles*352g/moles=125.84g
