Answer
We can put about 21.375g of Sucrose in a container, and dissolve until it reaches 250ml.
Work Step by Step
1. Find how much moles we need:
$n(moles) = C(M) \times V(L)$
$n(moles) = 0.250 \times 0.250$
$n(moles) = 0.0625$
2. Now, find how much is 0.0625 moles of $C_{12}H_{22}O_{11}$ in grams:
Molar Mass $(C_{12}H_{22}O_{11})$:
C: 12 * 12
H: 1 * 22
O: 16 * 11
144 + 22 + 176 = 342g/mol
$mass(g) = mm \times n(moles) $
$mass (g) = 342 \times 0.0625$
$mass(g) = 21.375g$
