What volume of a 6.0 m hcl solution is required to make 250.0 milliliters of a 1.5 m hcl?
0.38 liters
0.063 liters
0.25 liters
1.0 liters
1.5 liters

Option (d) is the correct answer.

Explanation:

When there are equal number of moles then molarity times volume of one solution equals the molarity times volume of another solution.

Mathematically,    

Since there are 1000 mL in 1 litre so, 250 mL equals 0.25 L. Therefore, calculate molarity as follows.

                                = 1 L

Thus, we can conclude that the volume of 1.5 M HCl is 1.0 L.

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 :
