20 g of an ideal gas contains only atoms of S and O occupies 5.6 L at NPT. What is the mol. wt. of gas ?
Mass of gas = 20 g
Pressure of gas = 1 atm
Volume of gas = 5.6 L
Temperature of gas = 273 K
Using ideal gas law,
P = pressure of the gas
V = volume of the gas
T = temperature of the gas
n = number of moles of the gas
R = gas constant = 0.0821
M = molar mass of gas
w = mass of gas
Now put all the given values in the formula, we get
Therefore, the molar mass of the gas is, 80.0475 g/mole
5.6 litres of a gas at N.T.P. are found to have a mass of 11 g. The molecular mass of the gas is

Vapour density of a metal chloride is 66. Its oxide contains 53% metal. The atomic weight of the metal is
When two aqueous solutions react together to give off solid product, this reaction is known as
At S.T.P. the density of CCl4 vapour in g/L will be nearest to
Which of the following transitions of electrons in the hydrogen, atom will emit maximum energy ?
The uncertainty found from the uncertainty principle (Δx.Δp = h/4 π) is
The number of atoms of hydrogen in 2 moles of NH3
The spectrum of He is expected to be similar to that of
The spectrum of an atom depends on the number of electrons present in it. Here, helium has two electrons, so the spectrum of Li+ (Z = 3) is similar to that of helium because both He and Li+ have two electrons.
