x L of N_(2) at STP contains 3xx10^(22) molecules. The number of molecules in x//2 L of ozone at STP will be

Assertion (A) : 1 c.c. of Nitrogen at STP contains 2.69xx10^(19) molecules. Reason (R ) : Molar volume of an ideal gas at STP contains Avogadro number of molecules.

The volume of a container is 10L, It is filled with O_2 at STP. IF the container is heated to 27^@C and then opened at a pressure of 75 cmHg, then what will be the mass of gas expelled? Mass of 1L of oxygen at STP is 1.43g .

"x" L of methane gas at STP contains 1.5xx10^(21) molecules. The number of molecules in "x" L of sulphur diocide at STP will be :

"x" L of methane gas at STP contains 1.5xx10^(21) molecules. The number of molecules in "x" L of sulphur diocide at STP will be :

O_(2) gas at STP contained in a flask was replaced by SO_(2) under same conditions. The weight of SO_(2) will be

O_(2) gas at STP contained in a flask was replaced by SO_(2) under same conditions. The weight of SO_(2) will be

SO_(2) at STP contained in a flask was replaced by O_(2) under identical conditions of pressure, temperature and volume. Then the weight of O_(2) will be.... Of SO_(2)
