    1. The problem statement, all variables and given/known data

    10. An ideal gas in a container has a pressure of 2.50 atm and a volume of 1 m3 at a temperature of 30oC. How many moles of gas are in the container?

    a. 20 moles
    b. 45 moles
    c. 62 moles
    d. 83 moles
    e. 100 moles

    2. Relevant equations

    PV=nRT

    3. The attempt at a solution

    2.5atm*1000L=n*8.134*303.15
    n=1.01 moles

    which is not in the options...what am I doing wrong??
