Answer:
The abundance of 35/17 Cl is 75% and 25% of 37/17Cl
Explanation:
The molar mass of an atom is defined as the sum of the masses of each isotope times its abundance, that is:
35.5amu = 35amu*X + 37amu*Y <em>(1)</em>
<em>Where X is the abundance of the 35/17Cl and Y the abundance of 37/17 Cl</em>
<em />
As there are just these 2 isotopes and the abundances of both isotopes = 1:
X + Y = 1 <em>(2)</em>
<em></em>
Replacing (2) in (1):
35.5 = 35X + 37(1-X)
35.5 = 35X + 37 - 37X
-1.5 = -2X
X = 0.75 = 75%
And Y = 100-75% = 25%
<h3>The abundance of 35/17 Cl is 75% and 25% of 37/17Cl</h3>
Answer:
It would probably be, something that can take up moisture to test it.
Explanation:
(to see if it can evaporate)
Answer:
The physical properties of a solution are different from those of the pure solvent. ... Colligative properties are those physical properties of solutions of nonvolatile solutes that depend only on the number of particles present in a given amount of solution, not on the nature of those particles.
