Answer:

140 L (3 sig-figs; includes the zero)*

Explanation:

PV = nRT => V = nRT/P

P = 0.800atm

V = ?

n = 5 moles

R =0.08206 L·atm/mol·K

T = -1°C = (-1 + 273)K = 272K

V = nRT/P = (5mol)(0.08206 L·atm/mol·K)(272K)/(0.800atm) = 139.5 L

*=> 140 Liters (3 sig-figs) => zero is a sig-fig b/c it was result of rounding 139.5 Liters to obtain 140 Liters.
