Mass of one atom is 6.66 xx 10^(-23) g. ...

Mass of one atom is `6.66 xx 10^(-23) g`. Its percentage in a hydride is 95.24. Thus, hydride is

A

`MH`

B

`MH_2`

C

`MH_3`

D

`MH_4`

Text Solution

Verified by Experts

The correct Answer is:
B
Mass of one atom = `6.66 xx 10^(-23) g`
Mass of `N_0` atoms = `6.66 xx 10^(-23) xx 6.02 xx 10^(23) g = 40 g`
Atomic weight of the element = 40
`{:("Element",%,"at.wt.","% at wt.","Ratio",),(M,95.24,40,95.24//40,2.381,1),(H,4.76,1,4.76//1,4.76,2):}`
Thus, hydride is `MH_2`.
