A sample of Ammonia gas at 650mmHg and 15 degree has a mass of 56.8g. calculate the volume occupied by the gas. Take N=14, H=1,R=8.3145jk.

The first thing we have to do is change and state all the units so that we can use our ideal gas law equation ().

650 mmHg is a pressure unit, we have to convert this to kiloPascals. We know that 760 mmHg gives us 101 kPa.

P = 86kPa

T = 15°C + 273K = 288K

R (Gas constant) = 8.31 kj/mol  

Molar mass of Ammonia () = (1 x 3) + (14) = 17g/mol

n (moles) = 3.34 mol

V = ?

Rearrange the equation to solve for Volume:

Substitute the values inside:

V =

Therefore 93 L of volume is occupied by the ammonia gas.

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.
