Question

1.004 mol Arsenic is how many atoms?

Answer 1

Answer:
`6.047* 10^(23)` atoms in 1.004 mol of arsenic

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 atoms, we use the equation:

`\text{Number of moles}=\frac{\text{Given atoms}}{\text {avogadro's number}}`

`1.004=(x)/(6.023* 10^(23))`

`x=1.004* 6.023* 10^(23)=6.047* 10^(23)`

Thus there are
`6.047* 10^(23)` atoms in 1.004 mol of arsenic
