Question

2As + 6NaOH 2 Na3ASO3 + 3 H2
If you start the above reaction with 3.25 moles of NaOH, how many moles of Na AsOs will
be produced?

Answer 1

Answer: 1.08 moles

Explanation:

For every 6 moles of sodium hydroxide consumed, 2 moles of sodium arsenite are produced.

This means that if 3.25 moles of sodium hydroxide are produced, we can set up the proportion:

3.25/6 = x/2, where x is the number of moles of sodium arsenite produced.

It follows that x = 1.08 moles.
