Rutherford bohr pretty sure
Mass of carbon / Mass of acetone x 100% = Percentage by mass Carbon<span>.
</span>Take the formula mass of acetone, <span>and then do the calculation.</span>
I believe the correct answer is "<span>d. releases, exothermic". When water evaporates, it is water releasing heat and energy, making it an exothermic reaction. Exothermic is defined as a reaction that releases heat with it.

Answer:
Because CLEARLY, each mole of glucose, C6H12O6 contains 6⋅mol oxygen atoms.
Answer:
8.18 M
Explanation:
The osmotic pressure (π) is a colligative property that can be calculated using the following expression.
π = M . R . T
where,
M: molarity
R: ideal gas constant
T: absolute temperature
The absolute temperature is 25 + 273 = 298 K.
The osmotic pressure (in atm) is:
π = M . R . T
200 atm = M . (0.08206 atm.L/mol.K) . 298 K
M = 8.18 mol/L
