Answer:

14.3 Litres

Step-by-step explanation:

Standard temperature and pressure denotes that a gas has the following:

P = 1 atm

T = 273K

According to this question, the mass of CO2 is 28g.

Using mole = mass/molar mass

Molar mass of CO2 = 12 + 16(2)

= 12 + 32

= 44g/mol

Mole = 28/44

= 0.64mol

To calculate the volume of CO2 at STP, we use the general gas law equation as follows:

PV = nRT

R = Gas law constant = 0.0821 Latm/molK

V = nRT/P

V = 0.64 × 0.0821 × 273/ 1

V = 14.3/1

V = 14.3 Litres
