How many mols of chlorine gas are in a box if the box is 29.0 L in size, at 1.8 atm of pressure and at a temperature of 300K?

2.15 moles  of chlorine gas

Explanation:

given data

volume = 29 L

temperature =  300 K

pressure = 1.8 atm

solution

we will apply here ideal gas equation formula

PV = nRT    .......................1

and here R is R = 0.082 l atm/ K mol

so n will be here as express as

n =  

n =

n = 2.15 moles  

so 2.15 moles  of chlorine gas
