Question

6NaCl + Ba3P2 - 3BaCl₂ + 2Na3P

If 17 moles sodium phosphide is produced, how many moles of sodium chloride is needed?
Round to the nearest hundredths.

Answer 1

From the balanced chemical equation:

6NaCl + Ba3P2 -> 3BaCl₂ + 2Na3P

We can see that for every 2 moles of Na3P, we need 6 moles of NaCl. This means there is a 3:1 molar ratio between NaCl and Na3P.

If 17 moles of Na3P is produced, we can calculate the moles of NaCl needed as follows:

17 moles Na3P * (6 moles NaCl / 2 moles Na3P) = 51 moles NaCl

Therefore, approximately 51 moles of sodium chloride are needed.
