How many moles are present in 0.23 kg of so2

There are 3.594 moles of sulfur dioxide.

Explanation:

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

There are 3.594 moles of sulfur dioxide.
