Calculate the freezing point of an aqueous solution containing `10.5g` of Magnesium bromide in 200 g of water, assuming complete dissociation of Magnesium bromide.
(Molar mass of magnesium bromide `=184 g mol ^(-1)`, for water `=1.86K kg mol^(-)`).

Explanation

To calculate the freezing point of an aqueous solution containing 10.5 g of magnesium bromide (MgBr₂) in 200 g of water, we follow these steps:

### Step 1: Calculate the number of moles of magnesium bromide.
To find the number of moles, we use the formula:
\[ \text{Number of moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \]
Given:
...
