Answer:
Probably it was ment to illustrate how significant and indivisible, being very small, atoms are and how each of them under normal conditions of presure and temperature find their own place eventually
Mass of chlorine =
(given)
Molar mass of chlorine =
Now, number of moles is defined as the ratio of given mass in gram to the molar mass of the compound.
Number of moles = 
Number of moles of chlorine =
= 
Now, according to significant figure rules, the least number of significant figure in the question identifies the number of significant figures in the solution.
Thus, in question, both digit have four significant figures, therefore, the answer must be in four significant figures.
Hence, number of moles of chlorine = 
Answer:
1. chloroplast
2. they prevent some proteins to function how they normally function
Explanation:
9,000 meters
Because density is altered by altitude, the helium balloon can reach a height of 9,000 meters, or 29,537 feet. Anything higher than this altitude will cause the helium within the balloon to expand and the balloon to pop.
