Answer:
1.0076g
Explanation:
We know that 1 dm³ = 1000ml
So 550ml = 0.55 dm³
We can find the number of moles using the formula:
Number of moles = Volume ÷ 24 dm³ [in rtp]
Number of moles = 0.55 ÷ 24 = 0.0229 mol
Now, we have to find the Mr in order to find mass of carbon dioxide.
Mr of CO₂ = 12 + (16 × 2) = 44
The formula for finding the mass in terms of Mr and number of moles is:
Mass = number of moles × Mr
∴Mass = 0.0229 × 44 = 1.0076g
