Question

27°C উয়তায় ও 57 cm চাপে 2.2 g CO2-এর আয়তন কত?​

Answer 1

Answer:

We need to find the density of carbon dioxide at given temperature and pressure.

For an ideal gas, we know

PV= nRT

We also know that, number of moles can be written as

n=(weight)/(gram molecular weight)

PV=(weight*R*T)/gram molecular weight

P* molecular weight =(weight*R*T)/volume

P*molecular weight = density *R*T

2.5*44=density *0.0821*300

Density = (2.5*44)/(0.0821*300) = 4.466 g/L

Density of CO2 at given conditions is 4.466 g/L
