A solution obtained by dissolving 342g of sugar `(C_(12)H_(22)O_(11))` in 1000 g water is.......molal.

Explanation

To solve the problem of finding the molality of a solution obtained by dissolving 342g of sugar (C₁₂H₂₂O₁₁) in 1000g of water, we will follow these steps:

### Step 1: Calculate the number of moles of sugar (solute).
The formula to calculate the number of moles is:
\[ \text{Number of moles} = \frac{\text{mass of solute (g)}}{\text{molar mass of solute (g/mol)}} \]
We know the mass of sugar is 342g. Now, we need to find the molar mass of sugar (C₁₂H₂₂O₁₁).
