Find the number of moles of argon in 452g of argon

Hello there! :)

We can use dimensional analysis to convert from grams to moles. Use the atomic weight of argon to determine the amount of g/mol.

Therefore, there are approximately 11.315 moles in 452 grams of argon.

a. they are both space stations

happy to

pls mark as brainliest.

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 :
