A closed cylinder is filled with CO₂ gas. The mass of CO₂ in cylinder is 4.4 g. Now express this amount of Carbon dioxide in following terms: a) no. of moles of CO₂ molecules
b) Volume at NTP
c) No. of 'gram molecule
d) No. of CO₂ molecules
e) No. of carbon atoms
f) No. of mole of Oxygen atoms
g) No. of molecules of oxygen

#a

Molar mass of CO2=44g/mol

given mass=4.4g

#b

0.1mol weigh:-

#c

No of molecules=Moles×Avagradro No

#d

No of molecules=

#e

#f

Lets write balanced equation

#g

It has 2oxygen atoms

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock
