Question

calculate the density of co2 gas which has pressure 745 mm at 65degree celsius

Answer 1

pressure=745mm
1 atm=760 mm hg
P=745/760 atm =0.8 atm
T=65°C =65+273=338K
R=0.0821 litre atm K^-1mol^-1
Mco2=44g/mol
appliying formula M =dRT/P
d=Mp/RT=44×0.98/0.0821×338
d=1.55g/l

Answer 2

Answer:

Density of CO2 will be 1.55 g/L.

Explanation:

Given that -

• Pressure = 745 mm
• Temperature = 65°C

To find -

• Density of carbon dioxide

Solution -

We know that,

1 atm = 760 mm Hg

→ P = 745/760 atm

→ P = 0.98 atm

Let's convert temperature into Kelvin now,

→ T = 65°C

→ T = 65 + 273

→ T = 338 K

R = 0.0821 litre atm K^(1) mol^(-1)

M (CO2) = 44 g/mol

Using formula,

M = dRT/P

→ d = MP/RT

→ d = (44 × 0.98)/(0.0821 × 338)

→ d = 1.55 g/L

Hence, density of CO2 will be 1.55 g/L.
