A 1.50 L portion of 0.100M sulfamic acid, HSO3NH2, is placed in the bottom of a 10.0 L glass lined stainless steel chamber. A dish containing 17.25g of solid NaNO2 is floated on the acid. A thin open ended U tube containing a pool of liquid mercury is connected to the chamber with a short length of gas-tight tubing. When the assembly is prepared as shown, the chamber is gently shaken to overturn the floating dish. The resulting reaction proceeds to completion and returns to room temperature.

HSO3NH2 (aq) + NaNO2 (s) = H2O (l) + N2 (g) + NaHSO4 (aq)

1) What mass of N2 will be produced by the complete consumption of the sulfamic acid?
a) 7.00 g
b) 4.20 g
c) 2.80 g
d) 0.00210 g
