Question

determine el volumen que ocupa 10 gramos de hidrogeno que se encuentra a 1248 mmHg y 127 grados centigrados

Answer 1

m = 10 g
Mm H = 1 g/mol
n = masa/ Mm
n = 10 g/ 2 g /mol = 5 moles

P = 1248 mmHg
1 atm ----- 760 mmHg
    x    -----  1248 mmHg
x =  1.642 atm
R = 0.0821 ( atm x L/ mol x K)
T = 127 + 273 = 400 K

P x V = n x R x T

V = 5 mol x  0.0821 ( atm x L/ mol x K) x 400 K

                            1.642 atm

v = 100 L
