Question

What is the mass of 6.023 x 1022 molecules of carbon dioxide​

Answer 1

Explanation:

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

$molecular \: weight = 12 + 32 = 44$

$mole = \frac{given \: weight}{molecular \: weight}$

$mole = \frac{6.022 \times {10}^{22} }{44}$

$no \: of \: molecules = moles \times na$

$no \: of \: molecules = \frac{6.022 \times {10}^{22} }{44} \times 6.022 \times {10}^{23}$

$no \: of \: molecules = 0.8242 \times {10}^{45} \\ no \: of \: molecules =8.242 \times {10}^{44}$
