Answer 2

Given,

Amount of SO2 gas at NTP = 11.2 liters

To find,

The total number of molecules in the given amount of SO2.

Solution,

We can simply solve this numerical problem by using the following process:

As per the mole concept;

1 mole of any gas at NTP has a volume = 22.4 liters

{Statement-1}

As per stoichiometry;

1 mole of any element contains Avogadro's number of atoms, that is, 6.022 x 10^23 atoms.

And, the molar mass of any element is equal to the atomic mass of the same element.

{Equation-2}

Now, according to the question;

22.4 liters of SO2 gas at NTP equals = 1 mole

22.4 liters of SO2 gas at NTP equals = 1 mole(according to statement-1)

=> 1 liter of SO2 gas at NTP equals = 1/22.4 moles

=> 11.2 liters of SO2 gas at NTP equals = (1/22.4×11.2) moles = 0.5 moles

Now, according to the statement-2;

1 mole of SO2 has = 6.022 x 10^23 molecules

=> 0.5 moles of SO2 has = (0.5×6.022 x 10^23) molecules = 3.011 × 10^23 molecules

Hence, 11.2 liters of SO2 gas at NTP contains 3.011 × 10^23 molecules.
