Answer:
2 molecules of CO2 weigh 88g.
Given,
The atomic weight of Carbon is 12g.
The atomic weight of oxygen is 16g.
To find,
Weight of two molecules of CO2
Solution,
The molecular weight of 1 molecule of CO2 is = (12 X 1) + (16 x 2)
Thus, the molecular weight of 1 molecule of CO2 = 44g.
Now,
weight of two molecules of CO2 = 44g X 2
thus, the weight of two molecules of CO2 is 88g.

Answer:
Two molecules of [tex]CO_{2}[/tex] weighs 88 g.
Explanation:
Molar mass of C = 12 g/mol
Molar mass of O = 16 g/mol
[tex]CO_{2}[/tex] contains 1 C and 2 O atoms.
∴ Molar mass of [tex]CO_{2}[/tex] = (1 × 12) + (2 × 16)
= 12 + 32 = 44 g/mol
⇒ Weight of 1 [tex]CO_{2}[/tex] molecule = 44 g
∴ Weight of 2 [tex]CO_{2}[/tex] molecules = 2 × 44
= 88 g
Therefore two molecules of [tex]CO_{2}[/tex] weighs 88 g.
