Solution

The correct option is D $22 g$
Number of moles $= \frac{m a s s}{m o l a r m a s s}$

Here, molar mass of $C O_{2} = 44 g / m o l$
and $n = 0.5 m o l$

Therefore, $m a s s = 0.5 m o l \times 44 g / m o l = 22 g$
Hence, mass of $C O_{2}$ is 22g

What is the mass of .5 mole of carbon dioxide gas ?

The correct option is D 22 gNumber of moles=massmolarmassHere, molar mass of CO2=44g/moland n=0.5molTherefore, mass=0.5mol×44g/mol=22gHence, mass of CO2 is 22g

What is the mass of $.5 m o l e$ of carbon dioxide gas ?

The correct option is D $22 g$
Number of moles $= \frac{m a s s}{m o l a r m a s s}$

Here, molar mass of $C O_{2} = 44 g / m o l$
and $n = 0.5 m o l$

Therefore, $m a s s = 0.5 m o l \times 44 g / m o l = 22 g$
Hence, mass of $C O_{2}$ is 22g
