Answer :
There are approximately 2.156 × 10²⁵ molecules in 35.8 moles of CH₄.
To calculate the number of molecules in 35.8 moles of CH₄, we can use Avogadro's number, which is approximately 6.022 × 10²³ molecules per mole.
Number of molecules = Number of moles × Avogadro's number
Plugging in the given value:
Number of molecules = 35.8 moles × (6.022 × 10²³ molecules/mole)
Calculating the expression:
Number of molecules = 2.156 × 10²⁵ molecules
Therefore, there are approximately 2.156 × 10²⁵ molecules in 35.8 moles of CH₄.
