The mass of KCl that exists in 20.3 g of solution containing 1.14% by mass of KCl is 0.23 g
From the question given above, the following data were obtained:
Mass of solution = 20.3 g
Percentage of KCl = 1.14% = 1.14 / 100 = 0.0114
<h3>Mass of
KCl =?</h3>
Cross multiply
Mass of KCl = 0.0114 × 20.3
<h3>Mass of KCl = 0.23 g</h3>
Therefore, the mass of KCl in the solution is 0.23 g

Answer:
violet
Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. Ultraviolet (UV) light—is radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 .
Explanation:
A substance that has a solubility of 12 grams/L of water would require 36/12 = 3 liters of water to dissolve 36 grams of the substance.
