How many mols of each do you have? mols = grams/molar mass
A is 4/4 = 1 mol
B is 4/32 = 0.125 mol
C is 4/2 = 2 mol
D is 4/18 = 0.222 mol
A mole of anything contains 6E23 particles.
A is 1 x 6E23 = ?
B is 0.125 x 6E23 = ?
C is 2 x 6E23 = ?
D is 0.222 x 6E23 = ?
The one with the most mols contains the most particles.
Which of the following contains the greatest number of particles?
A) 4g of helium gas
B) 4g of oxygen gas
C) 4g of hydrogen gas
D) 4g of water
