Answer:
0.6425 moles of is required to react with 25.7 grams of
.
Explanation:
mas of oxygen gas = 25.7 g
moles of oxygengas =
According to reaction given above, 5 moles of oxygen gas reacts with 4 moles of ammonia gas.
Then 0.8031 moles of oxygen gas will react with :
of ammonia gas
0.6425 moles of is required to react with 25.7 grams of
.
Answer:
The new atomic mass of oxygen is 64u
Explanation:
Given
Taking the mass by part on the scale of 1/12 gives atomic mass of oxygen = 16 u
Now, when the scale is changed from 1/12 to 1/3, the new mass would become
The new atomic mass of oxygen is 64u
