MCQ
If the mass table of atomic weights were established with oxygen atom assigned a value of $100,$ the atomic weight of carbon would be
- A$24$
- B$50$
- ✓$75$
- D$112$
✓
Answer
Correct option: C.
$75$
c
In the current system carbon is exactly 12 and oxygen is approximately $16 .$ So, if oxygen is assigned a value of 100 , then the mass of carbon can be calculated by following:
In the current system carbon is exactly 12 and oxygen is approximately $16 .$ So, if oxygen is assigned a value of 100 , then the mass of carbon can be calculated by following:
$12 / 16=X / 100$
$X=75$
So, the correct option is $C$
