Answer: 1 mole
Explanation:
One mole reacts because there is a 1:1 ratio between the potassium and water at the beginning of the equation. 2K+2H2O has a 1 to 1 ratio. If one potassium reacts there is one h2o that also reacts.
Answer:
There are 1.205x10²³ particles in 0.2 moles.
Explanation:
In order to <u>convert from moles to number of particles</u> we need to use <em>Avogadro's number</em>, which states the number of particles contained in 1 mol:
- 0.2 mol * 6.023x10²³ particles /mol = 1.205x10²³ particles
Thus, there are 1.205x10²³ particles in 0.2 moles.
