A_r = 35.5
The average atomic mass of Cl is the <em>weighted average</em> of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its <em>% abundance</em>).
Thus,
0.7553 × 35 u = 26.4 u
0.2447 × 37 u = <u>9.05 u</u>
TOTAL = 35.5 u
Answer
c.Conservation of matter
Answer:
the volume will decrease
Explanation:
an increase in temperature will lead to an increase in effective collision which also result in an increase in volume, when the temperature decreases, the volume will decrease
