Question

a sample of Ammonium Phosphate NH 34 bracket 3 PO 4 contains 18 moles of hydrogen atoms the number of moles of oxygen atoms in the sample is​

Answer 1

HELLO MATE

ANSWER ⏬

✏️✏️✏️

Given:

No. of moles of hydrogen atoms in ammonium phosphate sample = 18 moles.

Solution:

The formula for Ammonium phosphate is = (NH4)3 Po4

We can observe from the formula, that the number of hydrogen atoms = 12

Likewise, No. of N atoms = 3

No. of P atoms = 1

No. of O atoms = 4

This implies that 12 moles of Hydrogen correspond to 3 moles of oxygen.

Let x moles of oxygen correspond to 18 moles of hydrogen.

Therefore,  

X/4=18/12

x = 6

Answer 2

Thanks for asking the question!

ANSWER::

In the problem we can see that the no. of oxygen atoms is 3 times lower than the hydrogen atom and there are 3.18 moles of hydrogen atoms.

So,

Moles of oxygen atoms present in sample is= 3.18/3 = 1.06 moles

Hope it helps!
