How many atoms does 2.0 moles of He represent
Rudiy27

We use the following formula to calculate the number of atoms:

n (mol) = N(number of atoms) / NA

N(He) = n(mol) · NA

N(He) = 2,0 moles · 6.02·1023 = 12.04·1023 atoms

PV=nRT n=PV/RT

n=1 atm x 2,8 L/ 0,082 l atm/K mol x 273K

n= 0,125078173 mol
