= 24.3
The average atomic mass of X is the <em>weighted average</em> of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its <em>relative importance</em> (i.e., its % abundance).
Thus,
0.790 × 24 u = 18.96 u
0.100 × 25 u = 2.50 u
0.110 × 26 u = <u>2.86 u</u>
TOTAL = 24.3 u
∴ The relative atomic mass of X is 24.3.
Answer:
I think it's gold but I'm not sure, sorry
Explanation:
good luck tho :)
0.500 moles is roughly .5*6.022*10^23=3.011*10^23 atoms. This is independent of STP.
C: condensation
Examples are glasses fogging up and water droplets on a can of soda when it’s hot
