Answer: I think it’s B
explanation
Answer : The molar mass of the solute would be low.
Explanation :
Formula used for depression in freezing point is:

where,
= change in freezing point
= freezing point of solution
= freezing point of water
i = Van't Hoff factor
= freezing point constant
m = molality
= mass of solute
= mass of solvent
= molar mass of solute
From the formula we conclude that, when the freezing point of the solution read incorrectly that is freezing point of the solution is lower than the true freezing point then this means that change in freezing point would be high and the molar mass of the solute would be low.
Hence, the molar mass of the solute would be low.
Answer:
The answer is B. Compressions and rarefactions.
Explanation:
- <u><em>Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction.</em></u>
Answer:
The resulting solution contains approximately 666 g of water.
Explanation:
In the initial solution we have:
1g salt : 8g sugar : 200g water
This means that the ratios are:

In the final solution we have:
5g salt: xg sugar: yg water
The new ratios are:

Now we can calculate the amount of sugar in the final solution:

Finally, we calculate the amount of water:

Answer:
The electrons in H2O are not shared equally, making it a polar molecule. The molecules in flourine, F2, are shared equally, making it not a polar molecule.
