Answer:
The ration of molar concentration is "2.5".
Explanation:
The given values are:
Average density of salt water,
= 
Net pressure,
= 
Increase in pressure,
= 
Now,
The under water pressure will be:
= 
= 
= 
= 
hence,
The ratio will be:
= 
or,
= 
= 
= 
The water has surface tension
Answer:
A. Compounds
Explanation:
Firstly, don't let the word "pure" confuse you; this is pretty much irrelevant to the question.
The key to answering this question lies in "substance" and "more than one type of element chemically bonded."
Something you ought to memorize is that a substance is either an element or compound. Therefore, you can eliminate choices B./C.
Next, use the part of the definition that says "more than one type of element chemically bonded" to conclude that it's a compound. Not only is this the definition of a compound, but the fact that is says <em>more than one type of element</em> should automatically tell you that it is different from just a regular element (Choice D.).
Answer:
The volume of water in water bath is 1,011 Liters.
Explanation:
Length of the water bath, L = 1.85 m
Width of the water bath, W= 0.810 m
Height of the water bath ,H= 0.740 m
Height of the water in water bath, h= 0.740 m - 2.57 inches
1 m = 39.37 inch

Volume of the water in bath = L × W × h



The volume of water in water bath is 1,011 Liters.
