"17.83 moles CO"_2 have a mass of "784.7 g".

Explanation:

In order to determine the mass of a given numbers of moles of an element or compound, multiply the given moles by its molar mass.

Molar Mass of "CO"_2"

(1xx12.011 "g/mol")+(2xx15.999"g/mol")="44.009 g/mol CO"_2"

Multiply the given moles of "CO"_2" times its molar mass.

17.83cancel"mol CO"_2xx(44.009"g CO"_2)/(1cancel"mol CO"_2)="784.7 g CO"_2"

Number of moles = mass of substance -: molar mass

17.83 moles has been provided for you.

The formula of carbon dioxide is: CO_2.

The molar mass of carbon and oxygen is:
C = 12.0 g/mol
O = 16.0 g/mol
Therefore the molar mass of CO_2 is:
[1 xx 12.0 + 2 xx 16.0] = 44.0 g/mol.

The mass of CO_2 is:
44.0 xx 17.83 = 784.5 grams
Note: This answer is rounded to nearest one decimal place.

Overall, there are 784.5 grams in 17.83 moles of CO_2.
