An aqueous solution contains 32.7% kcl (weight/weight %). how many grams of water are contained in 100 g of this solution
igor_vitrenko [27]
Weight/weight percentage is the percentage of mass of solute from the mass of the whole solution
w/w % = 32.7 %
this means that in a solution of 100 g - mass of KCl is 32.7 g 
since solution is made of water and KCl
then the mass of water is - 100 - 32.7 = 67.3 g
therefore in 100 g of solution - 67.3 g of the solution is water

Savatey [412]

Answer:

The solar energy is converted to chemical energy by the process of photosynthesis - This is the true statement of the given question.

Explanation:

An ecosystem usually refers to the biological community comprising all the types of living species that are continuously interacting with the surrounding environment. Most of these ecosystems are solar-powered, and by this phrase, it means that there occurs the transformation of energy from solar to chemical energy which is taking place due to the process of photosynthesis. Both the terrestrial and the aquatic, are able to carry out this process in the presence of sunlight, water, and CO₂, and in return, it liberates food and oxygen into the ecosystem.

Thus, this statement satisfies the given phrase.

All other options are false as it does not justify the phrase.
