Molar mass CO₂ = 12 + 16 x 2 = 44.0 g/mol

1 mole ------------ 44.0 g
9 moles --------- ? ( mass CO₂)

mass CO₂ = 9 x 44.0 / 1

mass CO₂ = 396 / 1

= 396 g of CO₂

hope this helps!

Answer:

There are 396 g of \(CO_{2}\) in 9 mol of \(CO_{2}\)

Explanation:

Molar mass of \(CO_{2}\) = \((1\times atomic mass of carbon)+(2\times atomic mass of oxygen)\) = \((1\times 12 g)+(2\times 16 g) = 44 g\)

That means mass of 1 mol of \(CO_{2}\) is 44 g.

So mass of 9 moles of \(CO_{2}\) = \((9\times 44 g)= 396 g\)
