Fluorine gas can react with ammonia gas to produce dinitrogen tetrafluoride gas and hydrogen fluoride gas. This reaction is described by the following balanced equation:
5 F2 (g) + 2 NH3 (g) N2F4 (g) + 6 HF (g)

What mass of hydrogen fluoride gas is produced from 135 g of ammonia gas assuming that there is an ample amount of fluorine gas present for the reaction to be completed?
A.
38.3 g
B.
405 g
C.
52.9 g
D.
476 g

  1. massHFl=(6molesHFl/2molesNH3) *( 1moleNH3/17gNH3)*(135gNH3)*(19gFl/moleFl)
    = (6*1*135*19/2*17)=452 g hydrogen floride
