Upon fully dissolving $2.0 \ g$ of a metal in sulphuric acid,$6.8 \ g$ of the metal sulphate is formed. The equivalent weight of the metal is $...... \ g$.

The weight of $H_2SO_4$ in $150 \ mL$ of $N = 1/7$ solution is ........ $g$.

When $1.0 \ g$ of a metal nitrate is converted into $0.86 \ g$ of metal sulfate,what is the equivalent weight of the metal?

$3.011 \times 10^{22}$ atoms of an element weigh $1.15 \ g$. The atomic mass of the element is: (in $amu$)

$A$ metal oxide is reduced by heating it in a stream of hydrogen. It is found that after complete reduction,$3.15 \, g$ of the oxide yielded $1.05 \, g$ of the metal. We may deduce that:

If the mass table of atomic weights were established with oxygen atom assigned a value of $100,$ the atomic weight of carbon would be
