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.
