The density of water is 1 g/cm3. Brent used the following method to convert 1 g/cm3 to kg/m3. (1 kg = 1,000 g and 1 m = 100 cm)
What is the error in Brent's conversion method?

A - 1 kg should be written as 1 g.
B - (1 m)3 should be written as (1 cm)3.
C - 1,000 kg should be written as 1,000 g.
D - (100 cm)3 should be written as (100 m)3.

answer: c.

explanation:

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 :
