Answer: 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
The answer should be volts
