Answer 1

Answer: The number of moles of
`O_2` are 6.

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
`6.023* 10^(23)` of particles.

To calculate the moles, we use the equation:

`\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}`

Given mass = 192 g

Molar mass = 32 g/mol

`\text{Number of moles}=(192g)/(32g/mol)=6mol`

The number of moles of
`O_2` are 6.
