How many molecules of carbon monoxide, CO, are there in 1.448 moles of carbon monoxide? Enter a number. Watch your sig figs!

Explanation:

# molecules = Avogadro's num x num of moles

number of CO 6.02x10 23 x n CO

  = 6.02x10 23 )  x 1.044= 6.28x 10 23 molecules

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 :

2b2t

explanation:

2b2t
