Answer : The freezing point of the solution is, 260.503 K
Solution : Given,
Mass of methanol (solute) = 215 g
Mass of water (solvent) = 1000 g = 1 kg (1 kg = 1000 g)
Freezing depression constant = 
Formula used :
where,
= freezing point of water = 
= freezing point of solution
= freezing point constant
= mass of solute
= mass of solvent
= molar mass of solute
Now put all the given values in the above formula, we get
By rearranging the terms, we get the freezing point of solution.
Therefore, the freezing point of the solution is, 260.503 K
Hey there!
One mole contains 6.022 x 10²³ atoms.
We have 2 moles.
2.00 x 6.022 x 10²³ = 1.20 x 10²⁴
There are 1.20 x 10²⁴ atoms of oxygen contained in 2.00 moles of oxygen.
Hope this helps!
