**Question:** Sodium Phosphate is being added as \(\text{Na}_3\text{PO}_4\). How many mEq of sodium will be added as a result of using sodium phosphate?
Given: \(\text{Na} = 23\), \(\text{P} = 31\), \(\text{O} = 16\)

Answer :

Final answer:

9 mMol of Sodium Phosphate in the TPN formula will result in 9 mEq of Sodium, as the valence of Sodium is 1.

Explanation:

The TPN (Total Parenteral Nutrition) formula you provided indicates that Sodium Phosphate is added as 9 mMol. To convert this to milliequivalents (mEq), we need to multiply the millimoles (mMol) of Sodium Phosphate by the valence of sodium. Sodium (Na) has a valence of 1, so the milliequivalents of Sodium will be the same as the millimoles. Therefore, 9 mMol Sodium Phosphate will result in 9 mEq Sodium.
