How many moles of cuso4 are used to make 250 ml of a 0.50 m cuso4 solution?

B) 0.125 mol CuSO4.

Explanation:

M =  

moles solute

liters solution

and solve for moles solute. moles = M x L Be sure to convert milliliters to liters.

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 :
