Answer:

Add limewater

Explanation:

Ca(OH)₂ is about 1000 times more soluble than Mg(OH)₂

If you add limewater to the seawater, the magnesium ions will precipitate out as magnesium hydroxide.

Mg²⁺(aq) + 2OH⁻(aq) ⟶ Mg(OH)₂(s)

To answer this question, we can use the following equation:

$e=\frac{h*c}{lambda}$

where e is the energy change, h is Planck's constant, c is the speed of light (m/s), and lambda is wavelength in meters. So then we can plug in the information:

$e=\frac{(6.626x10^{-34}J*s)(2.998x10^{8}\frac{m}{s})}{1.08m}$

$e=\frac{1.9865x10^{-25}J}{1.08}$

$e=1.84x10^{-25}J$

So the energy that is omitted by the atom is $1.84x10^{-25}J$ .

You would have to use the ideal gas law for this:
PV=nRT
Pressure, Volume, n=moles, R gas constant, Temperature in Kelvin
P=nRT/V
(1.8mol)(62.36)(309K)/43.0L = 805mm Hg
