There are 0.18 mol of

#### Explanation:

This looks like the time to apply the Ideal Gas Law:

#color(blue)(|bar(ul(PV = nRT)|)# ,

where

#P# is the pressure#V# is the volume#n# is the number of moles#R# is the gas constant#T# is the temperature

We can rearrange the Ideal Gas Law to get

#n = (PV)/(RT)#
