Help!!
A sample of 0.2540 moles of hydrogen gas at S.T.P is heated such that no mass is lost. At 30.00 degrees Celsius the heat is removed and the vol of hydrogen gas was found to be 5.093L.
Determine the vol of hydrogen at stp

Respuesta :

I believe this a PV = nRT question whereas

you re write the formula and solve for volume

V = nRT/ P

then you input the values

P= pressure constant

V= x

n = moles = 0.2540

R = gas constant should be 8.314J mol

T = C degrees + 273.15 = K

solve for voume

make sure all units match

and use sig figs!!!!
