Question

How many grams of CO2 are in 9 mol of the compound? grams

Answer 1

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 2

There are 396 g of
`CO_(2)` in 9 mol of
`CO_(2)`

Step-by-step explanation:

Molar mass of
`CO_(2)` =
`(1* atomic mass of carbon)+(2* atomic mass of oxygen)` =
`(1* 12 g)+(2* 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* 44 g)= 396 g`
