There are four Hydrogen atoms in one molecule of Methane (CH₄).
And there are 6.022×10²³ molecules in 1 mole of CH₄.
So,
Number of Hydrogen atoms is 1 mole of CH₄ are,

= 6.022 × 10²³ × 4

= 2.4 ×10²⁴ Hydrogen Atoms

Now calculating for 2 moles,

As,
1 mole of CH₄ contains = 2.4 ×10²⁴ Hydrogen Atom
Then,
2 moles of CH₄ will contain = X Hydrogen Atoms

Solving for X,
X = (2 moles × 2.4 ×10²⁴ Hydrogen Atom) ÷ 1 mole

X = 4.8 × 10²⁴ Hydrogen Atoms

How are Newton's three laws of motion related

OLga [1]

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Answer: $5.6dm^3[/tex[ of gas is produced when 0.1 moles of magnesium nitrate is decomposed.Explanation:The balanced chemical equation is:
[tex]2NH_4NO_3(s)\rightarrow 2MgO(s)+4NO_2(g)+O_2(g)$

According to stoichiometry :

2 moles of $NH_4NO_3$ produce = 4 moles of $NO_2$ gas and 1 mole of $O_2$ gas

2 moles of $NH_4NO_3$ produce = 5 moles of gas

Thus 0.1 mole of $NH_4NO_3$ produce = $\frac{5}{2}\times 0.1=0.25moles$ of gas

Volume of gas produced = $moles\times {\text {Molar volume}}=0.25moles\times 22.4dm^3/mol=5.6dm^3$

Thus [tex]5.6dm^3[/tex[ of gas is produced when 0.1 moles of magnesium nitrate is decomposed.
