If Avogadro number \(N_{A}\), is changed from \(6 . 022 \times \left(10\right)^{23}\)\(\text{mol}^{- 1}\) to \(6 . 022 \times \left(10\right)^{20} ~\text{mol}^{- 1}\) this would change the:
1. | definition of mass in units of grams. |
2. | mass of one mole of carbon. |
3. | coefficient of chemical species in a balanced equation. |
4. | ratio of elements in a compound. |
The maximum number of atoms is present in which of the following -
1. | 1 g of Mg(s) | 2. | 1 g of O2 (g) |
3. | 1 g of Li(s) | 4. | 1 g of Ag(s) |
One mole of oxygen gas at STP is equal to:
(a) | 6 .022× 1023 molecules of oxygen |
(b) | 6.022 × 1023 atoms of oxygen |
(c) | 16 g of oxygen molecule |
(d) | 32 g of oxygen |
Choose the correct answer from the option given below:
1. (a) and (b)
