10 moles of CO2
do not contain :


(A) 120 g of C
(B) 6.022 × 1024 atoms of O

(C) 10 NA
molecules of CO2

(D) 20 gram-atoms of O.​

Answer 1

Answer:

Explanation:

Correct answer is option B

Answer 2

The incorrect statement is B.

Given: 10 moles of CO2.

To find: We have to find the wrong statement.

Solution:

• A) 1 mole of carbon dioxide contains 12 gram C atoms.

10 moles of carbon dioxide contains 120 gram C atoms.

• B) 1 atom of oxygen has $6.023×10^{23}$ atoms.

20 atoms of oxygen contain $12×10^{24}$ atoms.

• C) 1 mole of carbon dioxide contains NA molecules of carbon dioxide.

Thus 10 mole of carbon dioxide contains 10NA molecules of carbon dioxide.

• D) 1 mole of carbon dioxide contains 2 atoms of Oxygen.

Thus 10 moles of oxygen contain 20 atoms of oxygen.
