When multiplying by a constant, raise Kp to the power of that constant.
When the reaction is reversed, it gives the inverse of Kp.
Kp^(-1/2) = (7.8 x 10^-16)^(-1/2) = 3.6 x 10^7

Answer:
please give the answer choice.
Answer:
6.113 atm
Explanation:
Data provided in the question:
Molarity of the solution = 0.25 M
Temperature, T = 25° C = 25 + 273 = 298 K
Now,
Osmotic pressure (π) is given as:
π = MRT
where,
M is the molarity of the solution
R is the ideal gas constant = 0.082057 L atm mol⁻¹K⁻¹
on substituting the respective values, we get
π = 0.25 × 0.082057 × 298
or
π = 6.113 atm
Answer:
ten atoms of hydrogen are present in one mole of caffeine.
Explanation:
Molecular formula of caffiene is given which is C3H10N4O2. It clearly shows that ten atoms of hydrogen are present. One mole is amount equal to one molecular weight of a molecule which is derived from molecular formula. So as moecular formula has ten atoms of hydrogen, one mole of caffeine has 10 atoms of hydrogen.
