Answer:
14.3 Litres
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
