Question

Calculate the no. Of molecules in 0.1 moles of CO2.

Answer 1

Number of molecules

= no. of moles × N•

= 0.5 × 6.022×10^23

= 3.011 × 10^23 molecules

Answer 2

Explanation:

in $Co2$ molecule mass=$6+2×8\:gms$

in ${ 22 gms\:molecule =Na    }$

$\boxed{\blue {Na=6.022×{10}^{-23}    }  }$

${  1gms\:molecule =\frac{Na}{22}   }$

${0.1gms \:molecule =\frac{Na}{  22}×100   }$

so the answer of this questions is

$\implies {\red { \frac{6 .022×100}{22}  }  }$

$\implies{\red {   \frac{602.2}{22} } }$
