Which of the following statements is not correct?

A. 0.20 mole of O2 = 6.4 g

B. 0.75 mole of H2CO3 = 47 g

C. 3.42 moles CO = 95.8 g

D. 4.1 moles Li2O = 94 g

To answer the question above, multiply the given number of moles by the molar masses.

(A) (0.20 mole) x (32 g / 1 mole) = 6.4 grams O2

(B) (0.75 mole) x (62 g / 1 mole) = 46.5 grams H2CO3

(C) (3.42 moles) x (28 g / 1 mole) = 95.7 grams CO

(D) (4.1 moles) x (29.88 g / 1 mole) = 122.508 g Li2O

The answer to the question above is letter D.
