What is the density of a substance with a mass of 0.0450 kg and a volume of 26.4

1704.54 kg/m³.

Explanation:

d = m/V.

where, m is the mass of the substance.

V is the volume of the substance.

m = 0.045 kg.

V = 26.4 mL/10⁶ = 2.64 x 10⁻⁵ m³.

∴ d = m/V = (0.045 kg)/(2.64 x 10⁻⁵ m³) = 1704.54 kg/m³.

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.

the correct answer is:
