Answer:0.00019 moles

Explanation:Use the Ideal Gas Law formula:

PV=nRTRemember:

P= pressure (atm)V= volume (L)n= number of moles (mol)R= molar gas constant (8.314J*mol/K)T= Temperature (K)1. First rearrange the formula so that it would be easier to find the number of moles.

n=

2. Convert the Temperature from Celcius to Kelvin (remember the temperature is always used in Kelvin for the formula).

30°

C+ 273K= 303K3. Now substitude your values

n=

4. Find your value

n=0.0019
