Assuming that x is the mass of electron ...

Assuming that x is the mass of electron and y is the total mass of protons in `""_(8)O^(18)`, which of the following equations is correct for calculating the total mass of protons?

A

`y=18x-10`

B

`8y=(x)/(1837)`

C

`(y)/(8)=1837x`

D

`y=(1837x)/(18)`

Text Solution

Verified by Experts

The correct Answer is:
C
Mass of electron = x
Mass of protons = y
No. of protons in `""_(8)O^(18)=8`
Mass of one proton `=y//8=1837x`
`y=8 xx 1837x`
Hence, the correct option is (c).
