Answer:

28.1

Explanation:

Divide the percentage abundances by 100:

92.2% ÷ 100 = 0.922

4.7% ÷ 100 = 0.047

3.1% ÷ 100 = 0.031

multiply them by their corresponding mass number:

0.922×28 = 25.816

0.047×29 = 1.363

0.031×30 = 0.93

add them all together to get your final answer:

25.816 + 1.363 + 0.93 = 28.109

to one decimal place:

28.1

I hope that helps!!!

Which substance would have the highest melting point, based on electronegativity?
Mazyrski [523]

Answer:

H₂O

Explanation:

Based electronegativity, water H₂O will have the higher melting point from the given choices. The binding force between hydrogen and oxygen is greater than for the others.

  • In group 6, oxygen has the highest electronegativity.
  • It pulls the shared electron closer in the bond.
  • The high electronegativity between hydrogen and oxygen causes the elevated melting point between the two species.
