¿cual sera el volumen que ocupara 2g?

¿cual sera el volumen que ocupara 2g. De oxigeno a 20'C y 728torr ?

En resumen

V x P = n x R x T v = ? M = 2 g t = 20 + 273 = 293 K P = 728 torr 1 atm - - - 760 torr x - - - 728 torr x = 0. 96 atm R = 0. 0821 (atm L / mol K) n (mol) = masa / Mm Mm O2 = 32 g / mol n = 2 g / 32 g / mol = 0. 063 mol v = n x R x T ```````````` P V = 0. 063 mol x 0.

V x P = n x R x T

v = ?

M = 2 g

t = 20 + 273 = 293 K

P = 728 torr

1 atm - - - 760 torr x - - - 728 torr

x = 0.

96 atm

R = 0.

0821 (atm L / mol K)

n (mol) = masa / Mm

Mm O2 = 32 g / mol

n = 2 g / 32 g / mol = 0.

063 mol

v = n x R x T ```````````` P

V = 0.

063 mol x 0.

0821 (atm L / mol K) x 293 K ```````````````````````````````````````````````````````````` 0.

96 atm

V = 1.
