answer
0.37946 moles
explanation
at STP, there are 22.4 liters for every mole of gas, so divide the number of liters by 22.4 to find the number of moles
number of moles =
number of moles = 0.37946 moles
Planck's constant =
6.62607004 × 10-34 m2 kg / s
Explanation:
Step by Step explanation
The Planck constant, or Planck's constant, is a fundamental physical constant denoted h, and is of fundamental importance in quantum mechanics. A photon's energy is equal to its frequency multiplied by the Planck constant. Due to mass–energy equivalence, the Planck constant also relates mass to frequency. Wikipedia

Answer: A
jk D
Explanation: because its math
Under normal conditions, when salt is added to water THE SALT DISSOLVES IN THE WATER THEREBY INCREASING THE BOILING POINT OF THE WATER.
When salt is added to water, the sodium and the chlorine ions in the salt separate and attach themselves to water molecules, this leads to the dissolution of the salt. Dissolving salt in water automatically increase the temperature at which the water will boil; the temperature will be greater than 100 degree Celsius. <span />
