Question

What is the total number of moles of hydrogen atoms contained in 1 mole of (NH4)2C2O4

Answer 1

Simplified formula

$\\ \rm\Rrightarrow N_2H_8C_2O_4$

Let's count atoms of all

• N=2
• H=8
• C=2
• O_2

In 1 mol of compound hydrogen is of

$\\ \rm\Rrightarrow 8mols$

Answer 2

Formula =>$\sf N_2H_8C_2O_4$

• Now, Look at the number of hydrogen atoms..
• The number of hydrogen atoms is the number next to the symbol of Hydrogen i.e. H the number is H8.
• Thus, There are 8 moles of hydrogen in the compound!!~
