9-Two different compounds containing tin and oxygen have the following composition: A: 0.742 g of tin, Sn, and 0.100g of oxygen, O
B: 0.555 g of tin, Sn, and of 0.150 g of oxygen, O
Show that these masses are in agreement with the law of multiple proportions.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
