Solution :
According to the Graham's law of diffusion, we know that, the rate of the diffusion varies inversely to the molar mass of the gas, i.e.
Rate of diffusion, 
where, the 'M' is the molar mass of the gas.
Now in the case of the isotopes of the Krypton,
Atomic mass of 
= 80 AMU
Atomic mass of 
= 82 AMU
Atomic mass of 
= 83 AMU
So the ratio of the rate of diffusion of the three isotopes are :
Dividing the above three with the smallest number among the three i.e. 0.10976, we get the relative rates of diffusion.
∴
= 1.02 : 1.01 : 1
Hence the relative rate of diffusion are :

Generally the equation for Atom Transition is mathematically given by
Where
Rydberg constant 
Therefore
Answer :
Incorrect
Explanation : In the given solution set of Ax = b;
is set of all vectors to form w=
p +
here
is is any solution of the equation Ax = 0;
this stands to be incorrect, as the correct would only exists when some vector
p is found to be like this

1. a sulfur-32 atom contains 16 protons, 16 neutrons, and 16 electrons. what is the mass (in grams) of a sulfur-32 atom?
The mass in grams of a sulfur-32 atom is 32.
That is how the isotopes are identified, showing the mass number of the isotope, which is the sum of protons and neutrons: 16 protons + 16 neutrons = 32 mass number = mass in grams of the isotope.
2. the mass of a neutron is 1.67 x 10-24 g. approximately what number of neutrons would equal a mass of one gram?
divide 1 gram by the number of neutrons per gram:
number of neutrons = 1 g / 1.67 * 10 ^ - 24 g / neutrons = 0.5998 * 10 ^ 24 neutrons = 5.998 * 10 ^23 neutrons.
