Question

Which of the following statements is not correct?

Answer 1

Answer:

It's 4.1 moles Li2O = 94 g on Odyssey ware

Answer 2

Answer:

4.1 moles Li2O = 94 g (incorrect)

4.1 mole of Li2O = 122.6g(correct)

Explanation:

1. Molar mass of O2 = 32

0.2 mole of 32 = 0.2×32 = 6.4g (correct)

2. Molar mass of H2CO3 = 62.03

0.75 mole of 62.03 = 0.75×62.03 = 46.5g (47 is correct)

3. Molar mass of CO = 28

3.42 moles of 30 = 3.42×28 = 95.76 (95.8 is correct)

4. Molar mass of Li2O = 29.9

4.1 mole of Li2O = 4.1×29.9 = 122.59g (94g is incorrect)
