CO2 is not polar as in this case the same types of molecules
are pulling in the same as well as opposite direction. CH4 is also not polar as
there is no imbalance in the charge of the molecules. CBr4 is also not polar
because in this case also no imbalance in the molecular charges can be seen.
CHBr3 is a bit polar in nature because it has different kind of charges at its
opposite ends. S among the all 4 options CHBr3 is polar.
It is a physical property

Awnser: D,Newtons second law of motion
Answer:
234.68g
Explanation:
We understood from Avogadro's hypothesis that 1mole of any substance contains 6.02x10^23 atoms. Therefore, 1mole of Fe2O3 also contains 6.02x10^23 atoms
1 mole of Fe2O3 = (56x2) + (16x3) = 112 + 48 = 160g
Now, if 160g of Fe2O3 contains 6.02x10^23 atoms,
Therefore Xg of Fe2O3 will contain 8.83×10^23 atoms i.e
Xg of Fe2O3 = (160x8.83×10^23)/6.02x10^23 = 234.68g
