Sample Problem 12. If 1 g of sulphur dioxide contains r molecules, wha

1.	Sample Problem 12. If 1 g of sulphur dioxide contains r molecules, what will be the number of m1 g of methane? (S 32 u, O 16 u, C 12 u, H 1 u)
Answer» 1 mole of SO2= 64g 1g of SO2= -----mole? = 1/64 mole From the given data 1/64 moles sulphur dioxide contain x molecules We know that equal moles of all gases will have equal number of molecules. Hence 1/64 moles of Methane Contains x molecules of methane Now we should find out the number of moles in 1g of methane 1 mole of methane = 16g 1g of methane = ------Mole? = 1/16 mole Since,1/64 mole of methane = x molecules 1/16 mole of methane contains = -------molecules? = x * 64/16 = 4x molecules

Answer»

1 mole of SO2= 64g

1g of SO2= -----mole?

= 1/64 mole

From the given data 1/64 moles sulphur dioxide contain x molecules

We know that equal moles of all gases will have equal number of molecules.

Hence 1/64 moles of Methane Contains x molecules of methane

Now we should find out the number of moles in 1g of methane

1 mole of methane = 16g

1g of methane = ------Mole?

= 1/16 mole

Since,1/64 mole of methane = x molecules

1/16 mole of methane contains = -------molecules?

= x * 64/16 = 4x molecules
