What is the total number of molecules in 11.2 liters of N2 gas at STP
scoray [572]
Molar volume at STP = 22,4 L

1 mole -------------- 22,4 L
 x mole -------------- 11,2 L

x = 11,2 / 22,4

x =  0,5 moles of N2

1 mole --------------- 6,02.10²³ molecules
0,5 moles ------------ y molecules

y = 0,5 . 6,02.10²³

y = 3,01.10²³ molecules
