Molarity -

 Molarity (M) = (Number of moles of solute)/(volume of solution in litres)

 

- wherein

It is defined as the number of moles of the solute in 1 litre of the solution.

As we have learned in the mole concept .

Formula of molarity = \frac{(n)_{solute}}{V_{solution} (in\ lit)}

0.1 = \frac{\frac{wt}{342}}{2}

wt(C12H22O11) = 68.4 gram

 


Option 1)

17.1 g

Option 2)

68.4 g

Option 3)

136.8 g

Option 4)

34.2g
