What is the molality of a solution containing 0.25 g

of dichlorobenzene (C6H4Cl2) dissolved in 10.0 g of

cyclohexane (C6H12)?

Answer :  The molality of solution is, 0.170 mole/kg

Explanation : Given,

Mass of dichlorobenzene = 0.25 g

Mass of cyclohexane = 10.0 g

Molar mass of dichlorobenzene = 147.01 g/mole

Formula used :

Therefore, the molality of solution is, 0.170 mole/kg

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
