According to periodic trends, bismuth has the greatest atomic radius.
1.07 mol would be your answer
Answer:
In order to find the molecular formula from an empirical formula you must find the ratio of their molecular masses.
We know that the molecular mass of the molecule is 70
gmol-1
. We can calculate the molar mass of
CH2
from the periodic table:
C=12.01
gmol−1
H=1.01
gmol−1
CH2 =14.03
gmol−1
Hence we can find the ratio:
14.03
70
≈
0.2
Hg = (3.2 : 4.2) x 100% = 76.19%
O = (1 : 4.2) x 100% = 23.81%
