Question

question 9 of 10
2 (nh₄)₃po₄
ammonium phosphate
how many hydrogen atoms are in 2 (nh₄)₃po₄?
2
24
4
12

Explanation:

Step1: Analyze one - unit formula

In one unit of \((NH_4)_3PO_4\), the sub - script of \(H\) is 4 and there are 3 ammonium \((NH_4)\) groups. So the number of \(H\) atoms in one \((NH_4)_3PO_4\) is \(4\times3 = 12\).

Step2: Calculate for 2 units

Since we have 2 units of \((NH_4)_3PO_4\), the total number of \(H\) atoms is \(2\times12=24\).

Answer:

24
