Question

How many molecules are in 0.500 moles of H2

Answer 1

1.34 x 10 22 (22 has to be in the top right and small btw)

Answer 2

There are
`3.011* 10^(23) molecules` in 0.500 moles of hydrogen gas.

Step-by-step explanation:

Moles of hydrogen gas = 0.500 moles

1 mol =
`N_A=6.022* 10^(23)` atoms/ molecules, ions

Number of molecules of hydrogen in 0.005 moles :

`0.500* 6.022* 10^(23)=3.011* 10^(23) atoms`

There are
`3.011* 10^(23) molecules` in 0.500 moles of hydrogen gas.
