The two solutions that have similar solubilities at 40°C will be Na₂HAsO₄ and Na₂SO₄.

<h3>What is solubity ?</h3>

It is the ability of a solute to be dissolved, especially in water.

As the temperature increases the solubility of the gas generally decreases"

According to given information and graph attached as reference ;

  • Solubility of NaCl (sodium chloride) at 40°C is 36.3 grams.
  • Solubility of Na₂SO₄ (sodium sulfate) at 40°C is 48.8 grams.
  • Solubility of Na₂HAsO₄ (sodium arsenate dibasic) at 40°C is 48.9  
    grams.
  • Solubility of Ba(NO₃)₂ (barium nitrate) at 40°C is 14.1 grams.
  • Solubility of Ce₂(SO₄)₃·9H₂O (ceasium sulfate nonahydrate) at 40°C is 6.2 grams.

Answer:

6.25%

Explanation:

Given data:

Half life of lutetium-117 = 6.75 days

Percentage remaining after 27 days = ?

Solution;

Number of half lives = Time elapsed / half life

Number of half lives = 27 days / 6.75 days

Number of half lives = 4

At time zero = 100%

At first half life = 100%/2 = 50%

At second half life = 50%/2 = 25%

At 3rd half life = 25%/2 = 12.5%

At 4th half life = 12.5%/2 = 6.25%
