Nitric Acid is produced from nitric oxide, NO which in turn is prepared from ammonia by the ostwald process.

4NH3 + 5O2 -----> 4NO + 6H2O

What volume of oxygen at 35 degrees C and 2.15 atm is neeeded to produce 50.0 g of nitric oxide

T= 273+35 = 308 K
P = 2.15 atm
n= 50.0 g ( 1 mol/ 30 g)= 1.667 mol
R= 0.0821
V= ?

2.15 (V) = 1.67(.0821)(308)

ANSWER:
V= 19.64

Is this correct
