Question

The volume occupied at 27°C and 2 atm pressure of the gas evolved from 2ml of solid CO,Density of
solid CO, is 1.53 gm/ml
a) 856 ml
b) 950 ml
c) 1050 ml
d) 1200 ml​

Answer 1

Answer:

Explanation:

t= 270 C=543k

P= 2 atm. ( for CO2)

V= 2 ml (for CO2)

Also d CO2=1.53g/ml

=1ml CO2=1.52g

therefore 2ml CO2 =3.06g

CO2----------->CO2

 3.06g               |

 n=3.06/44=0.069mole

using ideal gas eq^n

pv=nRT

v=nRT/P

=0.069x0.0821x543/2

=1.5Ltr
