Answer:
I don't know
Explanation:
because the oceans already have a ton of water in them so they don't really need to absorb the water again that evaporates
B-Many earthquakes are concentrated in narrow zones at the centers of plates.
C-Many earthquakes are concentrated in narrow zones along plate boundaries.
D-Most earthquakes occur deep under the ocean.
(I was thinking C but i'm not sure...)
The answer is C-Many earthquakes are concentrated in narrow zones along plate boundaries.
C
Answer:
Explanation:
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
Rules for significant figures:
Digits from 1 to 9 are always significant and have infinite number of significant figures.
All non-zero numbers are always significant.
All zero’s between integers are always significant.
All zero’s preceding the first integers are never significant.
All zero’s after the decimal point are always significant.
The rule apply for the multiplication and division is :
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Thus for product of
In this problem, 3.2 has 2 significant figures and 5.00 has 3 significant digits thus product will have the least number of significant figures which is 2. So, the answer will be in 2 significant figures.
Therefore, the answer is
Answer: The volume of solution is 2248 ml
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml
moles of =
Now put all the given values in the formula of molality, we get
Therefore, the volume of solution is 2248 ml
