Question

Read the following statements carefully.
Statement-1 : One mole of carbon weighs 12 g.
Statement-2 : 0.5 moles of nitrogen gas contains
3.011 × 1023 atoms of nitrogen.
Now, choose the correct option.
(1) Both the statements are correct
(2) Both the statements are incorrect
(3) Only statement-1 is correct
(4) Only statement-2 is correct

Answer 1

I am sorry, but I think the answer is 3. One mole of carbon does weigh 12 grams. But, one molecule of nitrogen gas has 2 aromas as it is diatomic. Therefore, one mole of nitrogen gas will have 2 x 6 x 10^23 atoms. If one mole contains 2 x 6 x 10^23 atoms, then obviously half a mile will contain 6 x 10^23 atoms of nitrogen.

I hope this is the right answer. Please tell me if it is not.
