Question

How many molecules are in 6 moles of methane

Answer 1

Answer:

3.6 × 10^24 molecules

Explanation:

Concept: Moles and Avogadro's number

• We need to know that one mole of a compound has molecules equivalent to the Avogadro's number, 6.022 × 10^23.
• Therefore; 1 mole of a compound contains 6.022 × 10^23 molecules

In this case;

We are given 6 moles of Methane;

But 1 mole of methane = 6.022 × 10^23 molecules

Therefore;

Molecules = Number of moles × Avogadro's number

                 = 6 moles × 6.022 × 10^23 molecules/mole

                 = 3.613 × 10^24 molecules

                 =  3.6× 10^24 molecules

Thus, there are 3.6× 10^24 molecules  in 6 moles of methane.
