Which symbol replaces the unit of atomic mass, amu?

 The modern atomic weight scale is based on

The most abundant elements by mass in the body of a healthy human adult are:
Oxygen$(61.4 \%)$, Carbon$(22.9 \%)$, Hydrogen$(10.0 \%)$ and Nitrogen$(2.6 \%)$. The weight, which a $75 \mathrm{kg}$ person would gain if all ${}^1\mathrm{H}$ atoms are replaced by ${}^2\mathrm{H}$ atoms is,

The largest number of molecules is present in 

The mass of a molecule of water is

The ratio of masses of oxygen and nitrogen in a particular gaseous mixture is $1:4$. The ratio of their number of molecules is

The weight of $112 \mathrm{mL}$ of oxygen at $\mathrm{NTP}$ on liquefaction would be

The number of gram-atom of oxygen in $6.02\times {10}^{24}$ of $\mathrm{CO}$ molecule is
