The average atomic mass of the hypothetical element is the sum of the products of the isotopes and their percentage abundance. For this given,
                 atm = (84.95 amu)(0.371) + (86.95 amu)(0.629) 
                         = 86.208 amu
Thus, the average atomic mass of the element is 86.208 amu.

Mandarinka [93]
The experimental density of CO2 at STP is 0.10/0.056=1.78 g/L. The percent error equals to (1.96-1.78)/1.96*100%=9.18%. So the answer is 9.18%.
