Question

Given that P-31 is the only natural isotope of phosphorus, what is the mass of one P atom and the mass of Avogadro's number of P atoms?

Answer 1

`""^31P` 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*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*g`....
