Answer:
Explanation:
Hope this helps you
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.
