Question

which is not represented by 1 mole of nitrogen gas
I) 6.023*10 power 23
II) 22.4L N2 at STP
III) 6.023*10 power 23 nitrogen atoms
Iv 28g of nitrogen ​

Answer 1

Answer:

the odd one is potion 3

Explanation:

1 mole of nitrogen gas at STP has 2×6.022×10²³ atoms....

Answer 2

The correct option to the following question is (iii), which is 6.023 × 10²³ Nitrogen atoms.

• One mole is defined as the amount of substance that contains as many elementary particles as present in 12 grams (0.012 kg) of the carbon-12 isotope.
• One mole of nitrogen gas you have 6.023×10²³ molecules of nitrogen gas, N2.
• At STP ( standard temperature and pressure) is the condition at which one mole of any gas occupies 22.4L of volume and pressure is 1 atm.
• One mole is also defined as the ratio of the mass of an element to the molecular mass of the element. Therefore, one mole of nitrogen gas is equal to 28 grams of Nitrogen.

Therefore, all the above options satisfy the requirement of one mole except (iii) that is 6.023×10²³ Nitrogen atoms.
