How many molecules are in 20.0 L(liters) of SO2 at STP

Finger [1]

5.4 x 10²³ molecules

Explanation:

Given parameter

Volume of gas = 20L

Condition of reaction = STP

Unknown:

number of molecules

Solution:

The number of molecules of a substance is given by;

Number of molecules = Number of moles x avogadro's constant

Number of moles at stp = $\frac{volume of gas}{22.4}$

Number of moles of SO₂ = $\frac{20}{22.4}$ = 0.893mole

Number of molecules = 0.893 x 6.02 x 10²³ = 5.4 x 10²³ molecules
