Answer:

27 amu

Explanation:

The alpha particles is Helium nuclei.

Atomic mass is the sum of the neutrons and protons.

Helium have two protons and two neutrons thus its atomic mass is 4 amu.

₂He⁴

Sodium atom have 12 neutrons and 11 protons. Thus its mass number will be

23 amu.

When it combine with alpha particle it mass will be 27 amu.

23 amu + 4 amu = 27 amu.

Thus new sodium atom have 14 neutrons and 13 protons.

<span>Consider two solutions: solution X has a pH of 4; solution Y has a pH of 7. From this information, we can reasonably conclude that </span>the concentration of hydrogen ions (H⁺) or hydronium ions (H₃O⁺) in solution X is thousand times as great as the concentration of hydrogen ions or hydronium ions in solution Y.
Solution X: c(H⁺) = 10∧-pH = 10⁻⁴ mol/L = 0,0001 mol/L.
Solution Y: c(H⁺) = 10⁻⁷ mol/L = 0,0000001 mol/L.
0,0001 mol/L / 0,0000001 mol/L = 1000.
