Answer 2

The mass of CO₂ is 1.1g.

We have to find the mass of 560 ml of CO₂ gas at STP.

Standard temperature and pressure :

• STP is generally used to define the condition of temperature and pressure which is important for the measurements of chemical and physical process.
• At STP, temperature = 0°C or 273.15K, pressure = 1 bar

Given, volume of CO₂ = 560 ml = 0.56 L

molar mass of CO₂ = 44g/mol

temperature at STP , T = 273.15K

pressure , P = 1 bar = 0.987 atm

Using formula, PV = nRT

⇒ 0.987 atm × 0.56 L = n × 0.082 atm.L/mol/L × 273.15K

⇒ n = 0.02467 ≈ 0.025 mol

we know, no of moles of CO₂ = mass of CO₂/molar mass of CO₂

⇒ 0.025 = mass of CO₂/44g

⇒ mass of CO₂ = 0.025 × 44g = 1.1g

Therefore the mass of CO₂ is 1.1g.
