Is the statement correct or incorrect- 35.5g of chlorine contains `6.022xx10^(23)` molecules?

How many grams of hydrogen will contain 12.046xx10^(23) molecules?

The value of avagadros number is 6.022xx10^(23) .

The number of gram molecules of oxygenis 6.02xx10^(24) CO molecule is-

The number of gram molecules of chlorine in 6.02 xx 10^25 hydrogen chloride molecules is

The number of gm-molecules of oxygen in 6.02 xx 10^(24) CO molecules is

The total number of protons in 10 g of calcium carbonate is (N_0 = 6.023 xx 10^23)

How many molecules are there in a 3.46 g sample of hydrogen chloride, HCl? Note: The number of molecules in a sample is related to moles of compound (1 mol HCl = 6.023 xx 10^(23) HCl molecules). Therefore if you first convert grams HCl to moles, then you can convert moles to number of molecules).

At a constant temperature, a vessel of 1 litre capacity contains 10^(23)N_(2) molecules. If the rms velocity of the molecules be 10^(3)m//s , then determine the total kinetic energy of the molecules and the temperature of the gas.
