How many moles of hydrogen molecules (h2) are present in 9 x 1023 molecules of hydrogen?

1,5 moles of H₂

Explanation:

Avogadro's number is defined as a constant that relates the number of particles presents in 1 mole. This number is 6,022x10²³.

Thus, 9x10²³ molecules of hydrogen are:

9x10²³ molecules of hydrogen × (1 mole / 6,022x10²³molecules) =

1,5 moles of H₂

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
