Question

A sample of ammonium phosphate contain 3.18 moles of hydrogen atoms then what is the number of moles of oxygen atoms in the sample

Answer 1

Hey Mate

♣♣♣ Here's ur Answer ♣♣♣

You can simply use ratios.

1 ammonium sulphate ~ 4×3 H ~ 4O

For 3.18 H let it be x O

X=(3.18×4)÷(4×3)

Which gives uh 1.06

Hope this helps ✌✌✌✌✌

Answer 2

Let's count individual atoms in (NH4)3PO4
N=3
H=12
P=1
O=4

From this,we come to know that 12 moles of Hydrogen correspond to 3 moles of Oxygen.


Let x moles of Oxygen correspond to 3.18 moles of Hydrogen

so, x/4=3.18/12
or, x = 3.18 * 4 / 12
or, x = 1.06 mole

Therefore, 1.06 moles of Oxygen is present in the sample.

hope it'll help you :)
