Answer:
A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. At the same concentration, weak acids have a higher pH value than strong acids.

Add the atomic mass of each element present. (If there is more than one atom of an element, multiply the element's atomic mass by the number of that element's atoms.)
Answer:
There are 0.1387 moles of oxygen atoms.
Explanation:
First we <u>calculate how many moles of ammonium phosphate there are</u>:
- There are 3 nitrogen moles per (NH₄)₃PO₄ mole.
- There are 0.104 nitrogen moles
- Thus there are (0.104 mol N * ) 0.0347 moles of (NH₄)₃PO₄.
Finally we calculate<u> how many moles of oxygen atoms are there in 0.312 moles of (NH₄)₃PO₄</u>:
- There are 4 oxygen moles per (NH₄)₃PO₄ mole.
- There are 0.0347 moles of (NH₄)₃PO₄.
Thus there are (0.0347 mol (NH₄)₃PO₄ * ) 0.1387 moles of O.
