Question

One mole of sulphur dioxide represents which of the following?

P 22.4 litres at STP

Q 6.02 × \[10^{23}\] atoms

R 6.02 × \[10^{23}\] molecules

विकल्प

• Only P

• Only Q

• Both P and Q

• Both P and R

Answer 1

Both P and R

Explanation:

One mole of a gas occupies 22.4 L at STP and contains \[6.02\times10^{23}\] molecules. Each \[\mathrm{SO_2}\] molecule has three atoms, so the number of atoms is not \[6.02\times10^{23}\].
