Answer:
P = 28.5 atm
Step-by-step explanation:
PV = nRT => P = nRT/V
P = Pressure = ?
n = moles of sample = mass/molar mass = 26g/44g·mol⁻¹ = 0.619 mole CO₂
R = gas constant = 0.08206 L·atm/mol·K
T = temperature in Kelvin = (35 + 273)K = 308K
V = volume in Liters = 550 ml = 0.550 L
Pressure (P) = nRT/V
= (0.619 mole)(0.08206 L·atm/mol·K)(308K)/(0.550 L) = 28.5 atm
