Multiply first the mass given in kilograms by 1000 in order to convert it to grams.
                    (0.23 kg) (1000 g / 1kg) = 230 g
Then, divide the mass in gram by the molar mass of SO2
        molar mass of SO2 = 64.044 g/mol
Solving for the number of moles,
                        (230 g)(1 mol/64.044g) = 3.59 moles
Thus, there are approximately 3.59 moles of SO2 present in 0.23 kg of SO2. 

Answer:

There are 3.594 moles of sulfur dioxide.

Explanation:

[tex]n=\frac{m}{M}[/tex]

n = moles of compound

m =  mass of the compound

M = Molar mass of the compound

Mass of sulfur dioxide= m = 0.23 kg = 230 g (1 kg = 1000 g)\

Molar mass of sulfur dioxde = M = 64 g/mol

Moles of sulfur dioxide = n

[tex]\frac{230 g}{64 g/mol}=3.594 mol[/tex]

There are 3.594 moles of sulfur dioxide.
