Question

Calculate the mass of 10²³ molecules of CO₂ gas
​

Answer 1

Explanation:

$\frac{given \: molecules}{avogadro \: constant} = \frac{mass}{molar \: mass}$

$\frac{ {10}^{23} }{6.023 \times {10}^{23} } = \frac{mass}{44}$

$mass = \frac{44}{6.023} = 7.3 \: g$

Therefore, the mass of 10^23 molecules of CO2 is 7.3 g.
