Fill in the missing data in the following table.

Explanation

For `H_(2)O`
Given, number of moles =2 and mass = 36g
`therefore` Number of particles = number of moles `xx 6.022 xx 10^(23)`
`therefore` Number of moles of `CO_(2) = ("number of particles")/(6.022 xx 10^(23)`=0.5 mol
Mass of `CO_(2)`= moles of molar mass
`=0.5 xx 44=22g`
(`therefore` molar of `CO_(2)=12+2xx16=44`)
For Na-atom
Given, mass =115 g
Number of moles = `("Mass")/("molar mass")=115/23=5` mol
`therefore` Number of particles `=5xx6.022 xx 10^(23)=3.011 xx 10^(24)`
For `MgCl_(2)`
Given, number of moles =0.5
`therefore` Number of particles =`0.5 xx 6.022 xx 10^(23)=3.011 xx 10^(23)`
Mass = number of moles x molar mass
(molar mass of `MgCl_(2)=24+2 xx 35.5=24+71=95)`
`=0.5 xx 95=47.5`g
Thus, the completed is as
