Question

Calculate the density of co2 at 100c and 800 mm of hg pressure

Answer 1

Answer:

We know,

At STP,

pressure = 760 mm Hg

Given, pressure = 800 mm Hg

Pressure = (800/760) atm

T = 100 + 273 = 373 K

mass of CO2 = 44

We know that,

PV = nRT

PV = (w/m)RT

w/V = density, d

w/V = d = (Pm / RT)

(R = 0.0821 litre atm / K mol)

d = 800 * 44 / 760 * 0.0821 * 373 = 1.5124 g / litre

Therefore, density = 1.5124 g/litre

Explanation:

Answer 2

your answer is 1.5124 g/l
