Answer:
0.16 atm
Step-by-step explanation:
Let's look at the formula PV=nRT. First of all, T should be in kelvin, so let's add 273. Now solve for P so we get P = nRT/V.
Now let's plug these in...
P = (0.034 mol)(0.08206 L atm mol^-1 K^-1)(298 K)/5.1 L
After solving and rounding to sig figs we get 0.16 atm
