As we know that one mole contains 6.022 × 10²³ particles. And the number of particles are related to moles as,
# of Particles = Moles × 6.022 × 10²³ particles
In case of Zinc atoms,
# of Atoms = Moles × 6.022 × 10²³ Atoms/mol
Putting value of moles.
# of Atoms = 6.05 mol × 6.022 × 10²³ Atoms/mol
# of Atoms = 3.64 × 10²⁴ Atoms
Answer:
Solution
1.4 gm of CaO⟶n0.4 gm of Oxygen
1.0 gm of O2⟶3.5 gm of Ca
According to the law of definite proportions
n/m=y/x
⇒1.4/0.4=3.5.
⇒3.5=3.5
Explanation:
<h2>It can happen when liquids are cold or when they are warm. ... It turns out that all liquids can evaporate at room temperature and normal air pressure. Evaporation happens when atoms or molecules escape from the liquid and turn into a vapor. Not all of the molecules in a liquid have the same energy.</h2>

Answer:
C. 0.35cm
Explanation:
The length indicated by the arrow along the ruler should recorded be recorded as "0.35cm".
This is correct because when counting the measurement on the ruler, the first line on the ruler is 0.1cm, the second line is 0.2cm, and so on. The spaces between each line is 0.05cm. So, the arrow is pointing on the space between 0.3cm and 0.4cm.
Therefore, 0.3cm + 0.05cm = 0.35cm.(answer).
