1.00g of oxygen combine with 0.126 g of hydrogen to form H2O. 1.00 g of nitrogen combie with 0.216 g of hydrogen to form ammonia. Predict the weight of oxygen required to combine with 1.00 g nitrogen to form an oxide.i m a student

Answer 1

Which oxide? Any one of the several that are known? I will assume NO.
Note the following:
For H2O.
(0.126g H2/2 H atoms) x 16 = 1.00 g oxygen
and
(0.216g H2/3 H atoms) x 14 = 1.00 g N, so

(1.00/14) x 16 = ? g N to form NO.
