Hi, in this question we will discuss about reduced mass of hf.
00:04
We know molecular weight of h is 1 .008 gram per mole and molecular weight of 2 is 18 .998 gram per more.
00:12
So the reduced mass formula that is mu equal to m1 into m2 by m1 plus m2 where m represents the mass.
00:26
Now, putting the values, we will get 1 .008 into 18 .998 by summation of these two, that is 20 .006 gram per mole.
00:44
Now, the reduced mass should be in gram.
00:47
So, to convert it, that is in gram per mole, into gram 1 by n0, should be multiplied.
01:06
Multiplicated where n0 is avocado number so 1 .008 into 18 .998 by 20 .006 into 1 by 6 .023 into 10 to the power 23 we will have the reduced mass equal to 0 .159 into 10 to the river 26 26 kg for the second part we have given the force concern is 970 newton and is 0 .159 into 10 to the minus 26 kg for the formula that correlated frequency with force constant and reduced mass that would be 1 by 2 pi root over force constant by now putting all these formulas 10 to the minus 26 we will get frequency as as 1 .243 into the 4 second inverse so this is the answer of the second part for the third part we need to find out energy required from vibrational level 0 going to vibration level 1.
02:41
Now the energy of vibration level 1 would be 3 by 2 h new minus the energy of vibration level 0 is half h new...
