What sort of relationship is there between the molarity and the absorbance? what evidence is there for this claim?

The molarity of a solution is typically directly related to its absorption. This relationship is expressed through the Beer-Lambert law, and can be written as A=ecl. This is usually used in spectroscopy and research.

Hope this helps!

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
