Answer:
0.00726mol
Step-by-step explanation:
Using general gas equation,
PV = nRT
Where;
P = pressure
V = volume
n = number of moles
R = gas constant (0.0821 L atm mol/K)
T = temperature
First, we need to convert the units of each variable
Volume = 185mL = 0.185L
Pressure = 760.0 torr = 1 atm
Temperature = 98.6°F = 310.15K
PV = nRT
1 × 0.185 = n × 0.0821 × 310.15
0.185 = 25.46n
n = 0.185/25.46
n = 0.00726mol
