jeka57 [31]
Well. Yeah. Basically.

1 mole of any gas is 22.4 L. 

Not really sure if that answers your question but that's what i know. 
Anyway if we are talking about the size then usually gases are filled with empty space.

How many molecules are there in 31.8 moles of water?
Murljashka [212]

Answer:

31.8\ moles = 1.91 * 10^{25}\ molecules

Explanation:

Given

31.8 moles of water

Required

Determine the number of molecule

In standard units: 1 molecule of water is:

1\ mole = 6.022 * 10^{23}\ molecules

Multiply both sides by 31.8

31.8 * 1\ mole = 31.8 *  6.022 * 10^{23}\ molecules

31.8\ moles = 31.8 *  6.022 * 10^{23}\ molecules

31.8\ moles = 191.4996 * 10^{23}\ molecules

Express 191.4996 as a standard form

31.8\ moles = 1.914996 * 10^2 * 10^{23}\ molecules

Apply law of indices:

31.8\ moles = 1.914996 * 10^{2+23}\ molecules

31.8\ moles = 1.914996 * 10^{25}\ molecules

Approximate:

31.8\ moles = 1.91 * 10^{25}\ molecules
