Answer: it’s B
Explanation:
Answer:
The molar mass of the unknown compound is 202.40 g/mol.
Explanation:
Let the molar mass of compound be M.
The depression in freezing point is given by:
where,
= change in boiling point = 0.81 K
=Boiling point of the solution = 3.77°C
T = freezing point of the pure solvent here benzene =5.48°C
= freezing point constant = 5.12°C/m
m = molality =
M = 202.40 g/mol
The molar mass of the unknown compound is 202.40 g/mol.
Answer: false
Step by step explanation
<span> It showed that the atom contains a small dense nucleus. The reason why this can be concluded is that the experiment showed that alpha particles can for the most part pass right through the foil. This showed that the nucleus of the atom is very small and takes up a very small portion of the size of an atom since the nucleus is what would reflect the alpha particle. If atoms were not mostly empty space, the alpha particles would have been bounced back and the opposite of what was observed would have happened (all or at least the majority would be bounced back instead the majority getting through with only a small portion being reflected back).
I hope this helps. Let me know in the comments if anything is unclear.</span>
