Question

Calculate the number of molecules present in 4.4 g of carbon

dioxide. (at wt of C=12, O=16)
​

Answer 1

Number of molecules present in 4.4g of carbon

Number of moles = mass / molar mass

= 4.4 / 44

= 0.1 moles

Number of moles = moles × Avogadro's Number

$= > 1 \times 10 ^{ - 1} \times (6.022 \times 10 ^{23} )$

$= > 6.022 \times 10 ^{ - 1 + 23}$

$= > 6.022 \times 10 ^{22}$
