How many molecules are contained in 52.5 moles of C2H6?
please explain if you can

3.16x10²⁵ molecules

Explanation:

1 mol refers to the amount of a substance. The amount of C₂H₆ molecules (or any other substance) that are in one mol is given by Avogadro's number:

With that in mind we can calculate how many molecules are there in 52.5 moles:

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
