Question

The density of carbondioxide is equal to 1.965kgm-3 at 273k and 1atm pressure. Calculate molar mass of co2

Answer 1

Answer:

44

Explanation:

pV=nRT or pV=

M

w

RT or M=

V

w

p

RT

or M=d

p

RT

Here, d=1.964g/dm

g/cc

P = 76 cm = 760 mm Hg = 1 atm

R = 0.0821 L atm K

×82.1×273

=44

The molecular weight of CO

Answer 2

Answer:

molar mass= density*vol

vol at stp= 22.4

mol mass = 1.965*22.4=44g

1 mol co2 is 44grams

hence molar mass=1
