Pretty sure it's the Precambrian.
Ba3PO4 is not neutral, it is positive. (NH4)2SO4 is neutral, the charges cancel.
Mg2OH is not neutral, it is positive. LiF2 is not neutral, it is negative. CaOH is not neutral, it is positive. The answer is (NH4)2SO4, correct ions will have a neutral charge.
Answer:
59.42 ×10²³ formula units
Explanation:
Given data:
Number of moles of NH4NO3 = 9.87 mol
Number of formula units = ?
Formula:
Number of formula units = moles × Avogadro number
Solution:
Avogadro number = 6.02×10²³
Number of formula units = 9.87 × 6.02 ×10²³
Number of formula units = 59.42 ×10²³ formula units
