Un volumen de 3?

Un volumen de 3. 24 litros de un gas medidos a 124 grado c y 644 mmhg pesa 3. 86 g . Encuentre el peso molecular del gas .

En resumen

V x P = n x R x T R = 0. 0821 ( L atm / molK) T = 124 + 273 = 397 K P = 644 mmHg 1 atm - - - - 760 mmHg x - - - - 644 mmHg x = 0. 847 atm V = 3. 24 L n (mol) = masa / Mm n = V x P ```````` R x T n = 3. 24 L X 0. 847 atm ```````````````````````````````` 0.

V x P = n x R x T

R = 0.

0821 ( L atm / molK)

T = 124 + 273 = 397 K

P = 644 mmHg

1 atm - - - - 760 mmHg x - - - - 644 mmHg

x = 0.

847 atm

V = 3.

24 L

n (mol) = masa / Mm

n = V x P ```````` R x T

n = 3.

24 L X 0.

847 atm ```````````````````````````````` 0.

0821 ( L atm / molK) 397 K

n(mol) = 0.

0842

Mm = masa `````````` mol

Mm = 3.

86 g `````````` 0.

0842 mol

Mm = 45.

84 g / mol.
