176g

The first thing we need to do is calculate the mass of one mole of carbon dioxide, and we get:

(Mass of Carbon) + (Mass of 2 Oxygen atoms) = Molar mass

Mass = 12 + (2 × 16) = 44g

Therefore, carbon dioxide has a molar mass of 44 grams, which is the mass of the gas

In order to determine the mass of 4 molecules of carbon dioxide, we need to multiply it by 4 × 44 = 176g.

Hope this helps :)

Here we go ~

lets calculate Molar mass of [tex]{\sf CO_2} [/tex] :

[tex]\qquad \sf  \dashrightarrow \: Molar \: \: mass \: \: of \: \: C O _2 = 12 + 2(16)[/tex]

[ Molar mass of[tex]{\sf \: CO_2 } [/tex]= Molar mass of Carbon + 2×( Molar mass of Oxygen )]

[tex]\qquad \sf  \dashrightarrow \: Molar \: \: mass \: \: of \: \: C O _2 = 12 + 32[/tex]

[tex]\qquad \sf  \dashrightarrow \: Molar \: \: mass \: \: of \: \: C O _2 = 44 \: g[/tex]

[ i.e 1 mole of [tex]{\sf CO_2} [/tex] weights 44 grams ]

So, by unitary method :

[tex]\qquad \sf  \dashrightarrow \: 1 \: \: mole \: \: CO_2 = 44 \: \: g[/tex]

[tex]\qquad \sf  \dashrightarrow \: 4 \: \: moles \: \: CO_2 = (44\times 4) \: \: g[/tex]

[tex]\qquad \sf  \dashrightarrow \: 4 \: \: moles \: \: CO_2 = 176 \: \: g[/tex]

Therefore, 4 moles of CO2 weights 176 grams
