Answer: 1.12 Liters
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
1 mol of 
occupy = 22.4 L
Thus 0.05 mol of will occupy = 
Displacement reaction
Because Al goes to SO4 and
Cu goes from SO4 to Cu
This happens because Al is more reactive (higher up in the reactivity series) than Cu
The number of particles in one mole is given be Avagadro's number <span>6.022×10^23
Multiply by number of moles.
3 ×10^-21 mol * 6.022 ×10^23 molecules/mol = </span><span>1,807 molecules
(rounded to nearest whole number)
