Answer: A. The compound CuCl is 500 times less soluble in sea water than it is in pure water.
pure water.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in a equilibrium reaction, the equilibrium will shift in a direction so as to minimize the effect.
Thus when a common ion is introduced to an equilibrium reaction, the equilibrium will shift in a direction where the concentration of common ion is decreasing.
When common ion such as 
from NaCl in sea water is introduced to an equilibrium reaction, the equilibrium will shift in a direction where the concentration of common ion is decreasing i.e. in the left side and thus solubility of CuCl further decreases.

Percent composition is the quantity or number of parts of a component contained in 100 parts of the total.
Given the the total is 100 g, the reported quantities for each component are the same percent.
Then, the percent composition of each as part of the entire sweet peas is:
Carb: 14.5%
Sugar: 5.7%
Diet. fiber: 5.1%
Prot: 5.4%
Fat: 0.4%
The rest to make the 100% is supposed to be water.
You could also find the percent composition in dry basis, which is done in this way (this is not what the question asks but it is good to know it).
Total components without water: 14.5 + 5.7 + 5.1 + 5.4 + 0.4 = 31.1 grams
Now divide each content by the total (31.1) and multiply by 100.
I will do one example:
Carbs: [14.5 / 31.1 ] * 100 = 46.6%
Answer:
How many grams are in 0.50 moles of h2so4?
We assume you are converting between moles H2SO4 and gram. You can view more details on each measurement unit: molecular weight of H2SO4 or grams This compound is also known as Sulfuric Acid. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles H2SO4, or 98.07848 grams.
