Answer to Question #341948 in Organic Chemistry for Sofia Martinez

Question

How many moles are there in 8.25 x 1026 molecules of methane, CH4?

Answer 1

Solution:

One mole of any substance contains 6.02×10²³ atoms/molecules.

Therefore,

Moles of CH₄ = (8.25×10²⁶ molecules) × (1 mol / 6.02×10²³ molecules) = 1370 mol = 1.37×10³ mol

Moles of CH₄ = 1.37×10³ mol

Answer: 1.37×10³ moles of methane (CH₄)
