Answer: They form a Triacylglycerol
One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

Bài 1. Có 30g dung dịch NaCl 20%. Tính nồng độ % dung dịch thu được khi
a. Pha thêm 20g H2O
b. Cô đặc dung dịch để chỉ còn 25g.
We need to use the Ideal Gas Law to solve this problem: PV = nRT, where P is pressure, V is volume, n is moles, R is the gas constant, and T is the temperature in Kelvin.
Here, volume is V = 500 mL = 0.500 L; moles is n = 0.60 mol; R is 0.08206 atm/(mol * K); and temperature is T = 25 + 273 = 298 K. Plug these into the equation to solve for P:
P * (0.500 L) = (0.60 mol) * (0.08206 atm/mol * K) * (298 K)
P ≈ 29.3 atm
Hope this helps!
