Calculate the mass of carbon disulfide CS2, which occupies a volume of 0.2 liters at a pressure of 200 mm

Calculate the mass of carbon disulfide CS2, which occupies a volume of 0.2 liters at a pressure of 200 mm. rt. Art. and a temperature of 600C

Given:
V1 (CS2) = 0.2 l
P1 = 200 mm Hg. Art.
T1 = 600 ° C = 872 K

To find:
m (CS2) -?

1) Vn (CS2) = P1 * V1 * Tn / (T1 * Pn) = 200 * 0.2 * 273 / (872 * 760) = 0.016 l;
2) n (CS2) = V / Vm = 0.016 / 22.4 = 0.0007 mol;
3) m (CS2) = n * M = 0.0007 * 76 = 0.05 g.

Answer: The mass of CS2 is 0.05 g.
