What would be the mass, in grams, of 1.505 x 10^23 molecules of carbon disulfide (CS2)?

To Find :

The mass, in grams, of molecules of carbon disulfide (CS₂).

Solution :

Molecular mass of CS₂ = 76 gm/mol .

It means that mass of molecules of CS₂ is 76 gm/mol.

Let, mass of molecules of carbon disulfide (CS₂) is x.

So,

Therefore, the mass in gram is 19 gm.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
