The oxidation number for ba is -2
Answer:
0.48atm
Explanation:
Firstly, we need to know the mole ratio of the oxygen gas involved. To do this, we simply place the number of moles of the oxygen over the sum of both gases.
This would be 3/(3+7) = 0.3
Now, to get the partial pressure contributed by the oxygen gas, we simply multiply the 0.3 by the total pressure
Hence, the partial pressure of oxygen = the mole fraction of oxygen * the total pressure.
= 0.3 * 1.6 = 0.48atm
