Aluminum atoms are in 3.78 g of aluminum
02214076x10^23)8.4367659370640769254888x10^22 atoms, therefore there are 8.4367659370640769254888x10^22 atoms of Aluminum(Al) present in 3.78 grams of Aluminum(Al).
Explanation:
Answer:
<em><u>≅ 50, 909 nm</u></em>
Explanation:
Wavelength, λ = 
Given:
speed of light = 
f = 5.89 × 
∴ λ = 3×
/ 5.89 ×
= 0.0000509 m <em><u>≅ 50, 909 nm</u></em>
