Question

two flasks A and B of 500mL each are respectively filled with O2 and So2 at 300k and 1atm pressure the flask will contain?
a) the same no. of atoms
b)the same no. of molecules
c)more no. of moles of molecules in flask A as compared to B
d) the same amount of gases​

Answer 1

Answer:

C

Explanation:

more no of moles of molecules in flask A compared toB

Answer 2

Answer:

From the given when the two flasks "A and B" with 500mL each are respectively filled with$o_{2}$ and $S o_{2}$ at 300k and 1 atm "pressure" the flask will contain

Option (b) the same number of molecules.

Explanation:

As the temperature and pressure conditions are identical, each flask will have same "number of moles" of gas as the other one, irrespective of which gas it contains, and since "number of moles" is equal so the "number of molecules" will also be equal.

Boyle's law, Charles law, Avogadro's law can be combined to obtain a very important equation known as the ideal gas equation.  

$v \propto \frac{n T}{p}$ then,

Pv=nRT

This gas correlates pressure-temperature volume and number of moles of a gas.

Since the energy of work done can be expressed differently in different systems of units, the gas constant R will have different. The "numerical value" of R depends upon the "units" and the  "pressure and volume" .
