Answer:
12.01
Explanation:
(12.00*98.93% + 13*1.07%) /100% = 12.01
Answer:
The number of lines possible for SO2 is 3
Explanation:
The following Procedure should be followed when calculating the number of vibrational modes:-
- Identify if the given molecule is either linear or non-linear
- Calculate the number of atoms present in your molecule
- Place the value of n in the formula and solve.
SO2 is a non-linear molecule because it contains a lone pair which causes the molecule to bent in shape hence, The mathematical formula for calculating the number of non-linear molecule in a infrared region is (3n - 6) here n is the number of atoms in molecule.
hence for Sulphur Dioxide (SO2), n will be 3
<u> Therefore, The number of lines possible for SO2 is (3*3) - 6 = 3</u>
