Question

if 1/4 mass of C-12 atom is taken as 1u, what would be the mass of O ?

Answer 1

Answer:

sorry I dont know dear

sorrrrřrrrrrrrrrrrrrry

Answer 2

Answer:

32

Explanation:

1 mass unit is equal to a twelfth of a carbon-12 atom, and, as per this system, the mass of an oxygen atom comes out to be 16 mass units.

So, if the mass unit was defined to be 1/4 the mass of a carbon-12 atom, the value of the unit would be halved. So the previous mass of oxygen would need to be doubled in order to meet the same value as before.

So, the mass of an oxygen atom would be 32 (new) mass units.

Hope it helps u !!
