### Limiting Reactant Calculations Post-Module Assessment

I have a question regarding one of the questions on the "Limiting Reactant" audio-visual module.

20. How many moles of CO2(g) are produced when 1 kg of CaCO3(s) is used to neutralize an acid spill? The equation for the reaction at 1 atm and 25 degrees C is: CaCO3(s) + H2SO4(aq) ---> CaSO4(s) + CO2(g) + H2O(l)

Is the the information about the temperature and the unit of pressure relevant (1 atm and 25 degrees C)? I disregarded it when solving and I got the correct answer, so I am a little bit confused. If anyone else knows, that would be really helpful! Thanks!

The information about the temperature and pressure isn't really relevant right now

The temp and pressure numbers are just denoting that the reaction is taking place at a standard temperature and pressure, meaning all of the products and reactants will behave ideally:) Long story short, the reaction is happening in a totally normal state so it can be solved without accounting for anything other than the reaction itself.
