Answer 2

molar mass of O2 (Oxygen) = 2 X 16 => 32 grams per mole

Hence, mass of 3 moles of O2 will be 3 X 32 => 96 grams.

So, x moles of SO2 will have a mass of 96 grams.

x=?

molar mass of SO2= 32+ 2 X 16 => 64 grams per mole.

Hence, x=96/64

x=48/32

x=24/16

x=12/8

x=6/4

x=3/2

x= 1.5 moles

Hence, 1.5 moles of SO2 will have the same mass as 3 moles of oxygen.
