How many molecules are in 6 moles of methane

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.
