JEE Main 2005 — Some Basic Concepts Of Chemistry Question with Solution
From: AIEEE 2005
Question
If we consider that 1/6, in place of 1/12, mass of carbon atom is taken to be the relative atomic mass unit, the mass of one mole of the substance will
Choose an option
Show full solutionCorrect option: D
Correct answer
Ddecrease twice
Step-by-step explanation
Let Relative Atomic Mass is in short R.A.M then
R.A.M =
12
Now if we take 1/6 instead of 1/12 at first then the equation will become
6
as 6 is half of 12 then R.A.M will decrease twice.
R.A.M =
12
Now if we take 1/6 instead of 1/12 at first then the equation will become
6
as 6 is half of 12 then R.A.M will decrease twice.
