Answer:
Well, we take the quotient….
Number of moles=Number of sodium atomsNA, the Avocado number
Where NA=6.022×1023∙mol−1
And so … 24.088×10236.022×1023∙mol−1=??∙mol with respect to sodium ATOMS….and note the dimensional consistency of the answer. We wanted an answer in moles, and the quotient gave us an answer in…
1mol−1≡11mol=mol
….and this persuades us that we have not ballzed up too badly when we performed the arifmetik…
And what is the mass of this quantity of sodium?
