List the three subatomic particles that compose atoms and

Solution : (a) To calculate the mass of oxygen per gram of nitrogen in each compound Compound A : 30.82gN reacts with 17.60g O = 0.5710g Thus, in Compound A, 1g of N eacts with .5710g of O. Compound B : 30.82 g N reacts with 35.20 g O = 1.1622g Thus, Compound B, 1g o f N reacts with 1.1622g of O. Compound C : 30.82 g N reacts with 70.40 g O = 2.2842g Thus, Compound C, 1g of N reacts with 2.2842g o f O. Compound D : 30.82 g N reacts with 88.00 g O = 2.8552g Thus, Compound D, 1 g f N eacts with 2.8552g f O. Among these the
