Answer:
The answer to your question is: 63.5 u
Explanation:
Data Percent Molecular mass
63 Cu 69.2% 62.9296 u
65Cu 30.8% 64.9278 u
Average atomic mass = ?
Formula
Average atomic mass = (0.692 x 62.9296) + (0.308 x 64.9278)
= 43.55 + 19.99
= 63.5 u
Answer:
C. 101.2 L
Explanation:
N2 + H2= NH3
Balancing it,
N2 + 3 H2 = 2.NH3
(1 mol) (3 mol) (2 mol)
which means
1 molecule of nitrogen reacts with 3 molecule of hydrogen to form ammonia.
Likewise,
50.6 l of nitrogen reacts with 50.6 × 3= 151.8 l of hydrogrn to form 50.6 × 2= 101.2 l of ammonia.
