Question

What conversion factor will change moles CO2 to grams CO2? Moles H2O to molecules H2O?

Answer 1

Moles to Grams:

The given molecule is CO₂

The standard atomic weight of Carbon (C) is 12.01

The standard atomic weight of Oxygen (O) is 32.00

Now, the weight of CO₂ is:

$CO_2 = 12.01 \times (2\times 32)$

$\therefore CO_2 = 44.01 \ g$

Thus, 1 mole of CO₂ = 44.01 g of CO₂

Moles to Molecules:

$\frac{Given \ mole }{1 \ Mole} \times 6.022 \times 10^{23}$

Now, the give mole of water is 1

$\frac{1 \ mole \ of \ H_2O}{1 \ Mole \ of \ H_2O} \times 6.022 \times 10^{23} = 6.022 \times 10^{23} \ molecules$

Thus, 1 mole of H₂O = 6.022 × 10²³ molecules of H₂O
