pressure of 50 mL of hydrogen at STP?

Update:

and for tamara, thats what i thought to, but im not sure. and i was not given any other information but i believe i'm supposed to use the PV = nRT equation?

    STP means standard temperature and pressure. Standard temperature is 0 degrees celcius.

    Standard Pressure is 1 atm.

    so if it is at STP then it has to be 1 atm.

    Plug it into PV=nRT

    P=pressure (unknown)

    V=volume (.050 L )

    n=moles (.004) (found using density of hydrogen- .08988)

    R=gas constant (0.08206 L-atm/mol-K)

    T=Temperature (273.15 at STP)

    P=(.004)(.08206)(273.15)/(.050)

    P=1.79 atm

    don't you need to know moles of hydrogen or grams?
