Question

4.48L of CH4 at STP is equal to how many molecules?

Answer 1

4.48L of CH4 at STP is equal to 1.2×10^23 molecules

Answer 2

Number of molecules in given volume of methane are - 1.29*10^23 molecules.

1 mole of any compound is known to contain number of molecules equivalent to Avogadro's number. Avogadro's number is 6.022*10^23.

We also know 1 mole of gas occupies 22.4 litre volume at standard temperature and pressure conditions, which are 1 atm and 273K respectively.

Hence, we can conclude that 22.4 litre is equal to 1 mole and it contains 6.022*10^23 molecules.

So, 4.48 litre will contain 1.29*10^23 molecules.
