Answer 1

Answer:

1.5 moles.

for explanation refer to the attachment.

Answer 2

66 gm of CO₂ is equivalent to 1.5 moles of CO₂.

• The number of moles in a substance is given by the formula, n = Given weight / Molecular weight

where n represents the number of moles.

• Given weight of CO₂ = 66 gm

Atomic weight of C = 12 gm

Atomic weight of O = 16 gm

∴ Molecular weight of CO₂ = 12 gm + (2 × 16) gm = 12 gm + 32 gm = 44 gm

• Number of moles in 66 gm of CO₂ = 66 gm / 44 gm = 1.5

• Therefore, 1.5 moles of CO₂ is present in 66 gm of CO₂.
