Answer:
P = 30.1 atm
Explanation:
Given data:
Temperature of vessel = 25°C
Volume of vessel = 10.00 L
Moles in vessel = A + B = 5.25 mol + 7.05 mol = 12.3 moles
Total pressure inside vessel = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
25+273 = 298 K
P = nRT/V
P = 12.3 mol × 0.0821 atm.L/ mol.K × 298 K / 10.00 L
P = 300.93 / 10.00 L
P = 30.1 atm
Answer: Melatonin has been used safely for up to 2 years in some people. However, it can cause some side effects including headache, short-term feelings of depression, daytime sleepiness, dizziness, stomach cramps, and irritability. Do not drive or use machinery for four to five hours after taking melatonin.
