The unit of atomic mass,$amu$ is replaced by $u$,here $u$ stands for

The equivalent weight of $Zn(OH)_2$ in the following reaction is equal to its: $Zn(OH)_2 + HNO_3 \to Zn(OH)(NO_3) + H_2O$

In a reaction,the ferrous $(Fe^{2+})$ ion is oxidized to ferric $(Fe^{3+})$ ion. The equivalent weight of the ion in the above reaction is equal to:

If $V \ mL$ of the vapours of a substance at $NTP$ weigh $W \ g$,find the molecular weight of the substance.

If $1.2 \, g$ of a metal displaces $1.12 \, L$ of hydrogen at $STP$,the equivalent weight of the metal would be:

$0.1$ mol of the following given antiviral compound $(P)$ will weigh $......... \times 10^{-1} \ g$
$Given :$ molar mass in $g \ mol^{-1} H: 1, C: 12, N: 14, O: 16, F: 19, I: 127$
