Answer 2

Answer:

The correct answer is 0.18.

Explanation:

The relative atomic masses of carbon and oxygen are 12 and 16, respectively. Therefore, the relative molecular mass of carbon dioxide is 44.

1 mole of $CO_{2}$ = 6.022 × $10^{23}$ molecules = 44 grams

If, 1 mole of $CO_{2}$= 44 grams.

Then, X mole of $CO_{2}$ = 8 grams.

X = 8/44

X  = 0.18 moles

Hence, 0.18 moles is equivalent to 8 grams of CO2.
