Question

Solid arsenic reacts with oxygen gas to synthesize solid arsenic trioxide. How many moles of arsenic trioxide will be produced from 3.4 moles of oxygen gas?

Answer 1

Answer:

2.26 moles of As2O3 will be produced

Explanation:

The reaction is this:

4As (s) + 3O₂ (g)  →  2As₂O₃(s)

Ratio is 3:2. So, 3 moles of oxygen produce 2 moles of arsenic trioxide

3.4 moles of O2 would produce

(3.4 .2)/ 3 =2.26
