A reaction at −8.0°C evolves 854.mmol of boron trifluoride gas. Calculate the volume of boron trifluoride gas that is collected. You can assume the pressure in the room is exactly 1atm. Be sure your answer has the correct number of significant digits.

 The volume of boron trifluoride gas that is collected is 18.6 L

Explanation:

According to the ideal gas equation:

PV=nRT

P = Pressure of the gas = 1 atm

V= Volume of the gas= ?

T= Temperature of the gas in kelvin =

R= Gas constant =

n=  moles of gas=  854 mmol = 0.854 mol   (1mmol=0.001mol)

Thus volume of boron trifluoride gas that is collected is 18.6 L

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.
