Question

(a) Can there be a polyhedron with 9 vertices, 9 faces and 16 edges? If yes, then name it. (b) If a length of 100 m is represented on a map by 1 em, then what will be the actual distance corresponding to 3.75 cm?​

Answer 1

Answer:

A solution of acetic acid (CH3COOH), methanol (CH3OH), and water is prepared such that the mole fraction of acetic acid is 0.01335, and the mole fraction of methanol is 0.03288. The density of the solution is measured to be 0.9889 g/mL.
