What is the molar mass of p4010? solve

283.889044 g/mol

The molar mass of P4 O10 is 283.889044 g/mol. Adding the molar mass of each element gives us the molar mass of the compound.

Explanation:

the answer is the

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 :
