Question

How many mole of so2 have the same mass of 3molo of oxygen

Answer 1

Mole = mass given/molar mass

Let mass be x

For Oxygen

3 = x/16

x=48g

As SO2 have same mass as Oxygen then,

Molar mass of SO2= 32+32

                                = 64g

Mole = 48/64

mole = 0.65 mole of SO2

Answer 2

Answer:

1.5 moles

Explanation:

First, what is the mass of 3 moles of O2 = ?

molar mass of oxygen = 2 x 16 => 32 grams per mole.

So, 3 moles of O2 has a mass equal to 3 x 32 =>96 grams.

So, we now have to find how many moles of SO2 has a mass = 96 grams.

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

So, 96 grams of SO2 is 64/96 moles =>96/64 => 3/2 => 1.5 moles.

Hence, 1.5 moles of SO2 has the same mass as 3 moles of O2.
