Calculate the molecular mass of glucose $[C_{6}H_{12}O_{6}]$ molecule. (in $u$)

The atomic mass of a metal is $27$ and its equivalent mass is $9$. What is the formula of its chloride?

Isotope	Relative abundance $(\%)$	Atomic mass $(u)$
$^{12}C$	$98.8$	$12$
$^{13}C$	$1.18$	$13.1$
$^{14}C$	$0.02$	$14.1$

From the above data,what is the average molecular mass of $CH_4$ containing all isotopes of carbon,assuming hydrogen is only $^{1}_{1}H$? (Given that atomic mass of hydrogen $= 1.008 \ u$)

$1.5 \ g$ of $CdCl_2$ was found to contain $0.9 \ g$ of $Cd$. Calculate the atomic weight of $Cd$.

Many elements have non-integral atomic masses because:

When an element forms its oxide,oxygen constitutes $20\%$ of its weight in the oxide. What is the equivalent weight of the element?
