La densidad de un gas es 0?

Fórmulas :

P x V = n x R x T (Ley de los gases Ideales) (a)

D = m / v (b)

n (moles) = masa / Mm (c)

R = 0.

082 (L atm / mol K)

d = 0.

054 g / mL

T = 30 + 273 = 303 K

P = 988 / 760 = 1.

3 atm

1.

Convertir g / mL a g / L

d = 0.

054 g x 1000 mL ```````````` `````````````` 1 mL 1 L

d = 54 g / L

2.

Sustituir en la fórmula (a) los moles

P · V = m · R · T ```` Mm

Mm · P · V = m · R · T

Mm = m · R · T entonces : m / v = d se sustituye ````````````` V · P

Mm = d ·R · T `````````` P

Mm = 54 g / L · 0.

082 (L atm / mol K ) · 303 K `````````````````````````````````````````````````````` 1.

3 atm

Mm = 1032.

06 g / mol.
