Answer:
18.066 × 10²³ particles
Explanation:
Given data:
Number of moles = 3 moles
Number of particles = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
For 3 moles of substance:
One mole = 6.022 × 10²³ particles
3 mol × 6.022 × 10²³ particles/ 1 mol = 18.066 × 10²³ particles
PH=-log[H⁺]
pH=-log(1.87×10⁻¹³)
pH=12.72
I hope this helps. Let me know if anything is unclear.
Answer:
The moon jelly population increased there were either more births or fewer deaths in the population than before. ... If there are more energy storage molecules available to the moon jellies, they can reproduce more, resulting in more births. Fewer deaths would also cause the jelly population to increase.
Explanation:
<span>When the gases dihydrogen sulfide and oxygen react, they form the gases sulfur dioxide and water vapor. so the balanced equation is
</span>2H2S(g) + 3O2(g) → 2SO2(g) + 2H2O(l)
