The molecular mass of sucrose $(C_{12}H_{22}O_{11})$ is (in $g/mol$)

Use the data given in the following table to calculate the molar mass of naturally occurring argon isotopes:

Isotope	Isotopic molar mass $(g \, mol^{-1})$	Abundance (%)
$^{36}Ar$	$35.96755$	$0.337$
$^{38}Ar$	$37.96272$	$0.063$
$^{40}Ar$	$39.9624$	$99.600$

The heaviest atom amongst the following is

$0.126 \ g$ of an acid is needed to completely neutralise $20 \ mL$ of $0.1 \ N$ $NaOH$ solution. The equivalent weight of the acid is:

$0.126 \ g$ of an acid requires $20 \ mL$ of $0.1 \ N$ $NaOH$ for complete neutralization. The equivalent weight of the acid is:

When a metal oxide is heated in a stream of hydrogen,reduction occurs. After reduction,$3.15 \, g$ of the oxide yields $1.05 \, g$ of the metal. What can we conclude about the metal?
