""^31P31P is certainly the most abundant phosphorus isotope....

Explanation:

And it is a fact that one mole of phosphorus atoms has a mass of 31.0*g31.0⋅g....

TO find the mass of an individual phosphorus atom, we divide the molar mass by the Avocado number....

(31.00*g*mol^-1)/(6.022xx10^23*mol^-1)=5.15xx10^-23*g31.00⋅g⋅mol−16.022×1023⋅mol−1=5.15×10−23⋅g....
