D neutrons. Theoretically, isotopes have different atomic mass but they do have a similar no. of protons. Having said that, subtracting protons with the different atomic masses results in different no. of neutrons.
Answer : The number of plates and plate height is, plates and respectively.
Explanation : Given,
Retention time = 407 s
Width of a base = 13.0 s
Length = 12.2 m
First we have to calculate the number of plates.
Formula used :
where,
N = number of plates
= retention time
w = width of a base
Now put all the given values in the above formula, we get:
plates
Now we have to calculate the plate height.
Formula used :
where,
H = height of plate
L = length
N = number of plates
Now put all the given values in the above formula, we get:
Thus, the number of plates and plate height is, plates and respectively.
Molar mass is the relationship of number of grams of a substance in 1 mole.
Answer:
The answer to your question is: less than
Explanation:
Some properties of matter depend on the amount of matter in a sample others do not.
Extensive properties: are properties that depend on the amount of matter in a sample. Ex. size, volume
Intensive properties: are properties that do not depend on the amount of matter in a sample. Ex. color, temperature, density, solubility, boiling point.
Then in your question boiling point does not depend on the amount of matter, then the boiling points will be the same as in number 1.
