Question

Fill the following table:

Sl. No.	Name	Symbol/ formula	Molar mass	Number of particles present in molar mass
$1$	Atomic oxygen		$16 g$	$6.022 \times 10^{23}$ atoms of oxygen
$2$	Molecular oxygen
$3$	Sodium
$4$	Sodium ion		$23 g$
$5$	Sodium chloride			$6.022 \times 10^{23}$ units of sodium chloride
$6$	Water

Accepted Answer

A symbol is the one or two letter abbreviation for the name of an element. We know that, one mole of any substance contains Avogadro number of particles. Therefore, using this data, we can fill the following table as,

Sl. No. Name Symbol/ formula Molar mass Number of particles present in molar mass

$1$ Atomic oxygen $O$ $16 g$ $6.022 \times 10^{23}$ atoms of oxygen

$2$ Molecular oxygen $O_{2}$ $3$ $6.022 \times 10^{23}$ molecules of oxygen

$3$ Sodium $Na$ $23 g$ $6.022 \times 10^{23}$ atoms of sodium

$4$ Sodium ion ${Na}^{+}$ $23 g$ $6.022 \times 10^{23}$ ions of sodium

$5$ Sodium chloride $NaCl$ $58.5 g$ $6.022 \times 10^{23}$ units of sodium chloride

$6$ Water $H_{2} O$ $18 g$ $6.022 \times 10^{23}$ molecules of water
