Calculate the number of atoms in each of the following
a. `52 mol` of `He`
b. `52 u` of `He`
c. `52 g` of `He`

Text Solution

Verified by Experts

1 mol of He `-= 4g -=6.022 xx10^23` He atoms
(ie) 4g of He contains `6.022xx10^23` He atoms
`therefore` 52 g` of He contains `=(6.023xx10^23xx52)/(4)`
`=7.83xx10^24`.
52 g of He contains `7.83xx10^24` He atoms.
