Answer:
0.473 moles
Explanation:
(2.85x10e23)/(6.02x10e23) = 0.47342
Compounds of hydrogen exhibit a relatively large kinetic isotope effect.
The phenomenon known as the kinetic isotope effect (KIE) is brought on by the variable reaction speeds that are displayed by isotopically substituted compounds. When it comes to studying reaction kinetics, mechanisms, and solvent effects, isotope effects like KIEs are invaluable tools in both physical and biological sciences.

The replacement of hydrogen with deuterium is a highly frequent isotope substitution. The ratio kH/kD, which describes this as a "deuterium effect," is used to measure it. Due to the proportion, significant effects are observed.

We can use the ideal gas law equation to find the pressure
PV = nRTwhere
P - pressure
V - volume - 2.6 x 10⁻³ m³
n - number of moles - 0.44 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 25 °C + 273 = 298 K
substituting the values into the equation,
P x 2.6 x 10⁻³ m³ = 0.44 mol x 8.314 Jmol⁻¹K⁻¹ x 298 K
P = 419 281.41 Pa
101 325 Pa is equivalent to 1 atm
Therefore 419 281.41 Pa - 1/ 101 325 x 419 281.41 = 4.13 atm
Pressure is 4.13 atm
Answer:
The answer to your question is: They are stronger than those in water.
Explanation:
When a substance is heated, heat is breaking forces among molecules like hydrogen bonds, london forces, van der waals forces, etc, if a substance has a lot of these forces, the boiling point will be higher because more forces must be broken.Then, glycerol must have stronger forces than those of water.
The number 7 is the coefficient
