According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given molecules}}{\text{Avogadros number}}$

given molecules = $7.03\times 10^{24}$

Putting in the values we get:

$\text{Number of moles}=\frac{7.03\times 10^{24}}{6.023\times 10^{23}}=11.7moles$

mass of $CO_2=moles\times {\text {Molar mass}}=11.7mol\times 44g/mol=514.8g$

The mass in grams is 514.8.
