What is the molar volume of 3.01 x 10(23) molecules of ethane (C2H6)?

Answer 1

Luna Chen

At STP, a mole of any gas occupies 22.4 L of volume.

22.4 L is equal to one mole of gas. (a)

one mole of gas has 6.02 x #10^ 23# particles( Molecules) ..... (b)

We obtain by equating (a) and (b).

6.022 x #10^ 23# particles (Molecules) = 22.4 L

Making conversion factors 22.4 L / 6.02 x #10^ 23# particles or

6.02 x #10^ 23# particles / 22.4 L

We will use the conversion factor that, when multiplied by the given number, yields L as the final unit since we want to change the number of molecules into L.

3.01 x #10^23# particles x 22.4 L / 6.02 x #10^ 23# particles

11.2 L

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
