Many of the atomic masses listed on the periodic table are decimal values because it's the weighted average mass of all of the isotopes of that element.
Answer: thermochromism, too hot of temperature or long exposure to high temperature may completely degrade the color of an object. In other instances, an object or sample changes to another shade of color until it stabilizes back to room temperature.
Explanation:
M(S)=1 g
m(O)=1.5 g
M(S)=32 g/mol
M(O)=16 g/mol
n(S)=m(S)/M(S)
n(O)=m(O)/M(O)
n(S)=1/32=0.03125 mol
n(O)=1.5/16=0.09375 mol
S : O = 0.03125 : 0.09375 = 1 : 3
