Answer: The mass percent by volume is 101.6%
Explanation:
The solution concentration expressed in percent by volume means that the amount of solute present in 100 parts volume of solution.
It is represented in formula as :
mass percent by volume =
Given : mass of glucose = 330.1 g
volume of solution = 325 ml
Thus mass percent by volume =
Thus the mass percent by volume is 101.6%
7 different types of tide
Answer:
c. Mercury is used in barometers because it has a high density
Explanation:
Chemical change -
It refers to any change in a chemical process , where there is formation of any new substance , is referred to as a chemical change .
The indication of any chemical change is the formation of some new substance.
Hence, from the question,
The process which does not involve chemical change is -
The use of mercury in barometer , to measure pressure , in this process no new substance is formed i.e. , now change in mercury.
